摘要： The first (T.sub.1) and the second (T.sub.2) output transistor of an amplifier arrangement are push-pull driven by means of a drive circuit (10) having two transistors (T.sub.11, T.sub.12) which are each loaded by a current source (T.sub.13, T.sub.14). Currents which are a measure of the currents flowing through the first (T.sub.1) and the second (T.sub.2) output transistor are generated by first (20) and second (30) current measuring means. These currents are applied to a negative feedback means (40) which controls the current intensity of the current sources (T.sub.13, T.sub.14) in such a way that the harmonic mean value of the currents flowing through the first (T.sub.1) and the second (T.sub.2) output transistor is substantially equal to a reference value.

摘要： A amplifier circuit comprises first transistor (T.sub.1) and a second transistor (T.sub.2) whose emitters are each connected via a first resistors (R.sub.1) to a point (2) which is connected to the power-supply terminal (3) by means of a current source (1). The bases of said transistors are connected to input terminals (4,5) and via a second resistor (R.sub.2) each to the base of a third transistor (T.sub.3) whose emitter is connected to the terminal (2). The linearity of the circuit is improved by arranging a fourth transistor (T.sub.4) and a fifth transistor (T.sub.5) in series with the collector-emitter paths of the first transistor (T.sub.1) and the second transistor (T.sub.2) which fourth and fifth transistor have their bases connected to a reference terminal (7) and have their emitters interconnected by means of a third resistor (R.sub.3).

摘要： In the case of amplifier circuits realised in modern MOS technology, non-linear distortion occurs as a result of the high field strengths in the channel region due to the small dimensions. This distortion is eliminated and noise is reduced in that the amplifier circuit comprises a first series combination of first and second MOS transistors, and a second series combination identical with the first series combination and forming a long tailed pair circuit with the latter. The long tailed pair circuit includes an additional differential amplifier having its output connected to the gate electrode of a load transistor of the long tailed pair circuit by way of a voltage divider. The transistors in the long tailed pair circuit are mutually identical.

摘要： An integrated circuit includes a sense amplifier which has an equalizing effect on voltages on the inputs of the sense amplifier, in particular during readout of the sense amplifier. The sense amplifier includes a parallel connection of a first and second current branch, each current branch including a control transistor, the source of which is connected to a relevant input, and the gate of which is connected to the drain of the control transistor in the other current branch, and a load transistor, whose gate receives a selection signal being connected in each said current branch in series with the control transistor. During readout, the gate of the load transistor is driven so as to make the channel of the load transistor conductive.

摘要： In a current-mode transconductor-C integrator, the non-linearity of the voltage-to-current conversion of a transconductor is corrected by means of a differentiator which supplies a current (i.sub.d) which is proportional to the derivative of a current (i.sub.f) which in turn is proportional to the transconductor output current (i.sub.out), with respect to the transconductor control (v). An input current (i.sub.in) is divided by the current (i.sub.d) by means of a current divider. The resultant quotient current (i.sub.q) is applied to an integrating capacitor across which a voltage (v) is built up. This voltage is converted into the output current (i.sub.out) by the transconductor. This results in an output current (i.sub.out) which is linearly proportional to the integral of the input current (i.sub.in) without the distortion usually caused by the non-linear voltage-to-current characteristic of the transconductor.

摘要： A current-source arrangement supplying a current which increases directly proportionally to the supply voltage (V.sub.S) and which is suitable for operation with supply voltages above approximately 0.7 V, comprises a first resistor (R.sub.10 =R) in which a current (V.sub.S -V.sub.BE)/R flows, which current is supplied by a first transistor (T.sub.10) via a first current-mirror circuit (T.sub.11, T.sub.12) and a second current-mirror circuit (T.sub.13, T.sub.14). A second resistor (R.sub.2 =R) is arranged in parallel with the base-emitter junction of the input transistor (T.sub.11) of the first current-mirror circuit (T.sub.11, T.sub.12), through which second resistor (R.sub.2) a current V.sub.BE /R flows which is supplied by the first transistor (T.sub.10) via the collector-base interconnection of the input transistor (T.sub.11). The total current flowing through the first transistor (T.sub.10) is then equal to V.sub.S /R. This current can be taken from the collector terminals (15A, 15B) of the transistors (T.sub.15A, T.sub.15B), whose base-emitter junctions are connected in parallel with the base-emitter junction of the first transistor (T.sub.10).

摘要： An electronic data processing circuit uses current mode signalling on a communication conductor, wherein a receiver supplies current to the communication conductor to try and keep a voltage on the conductor constant and measures the current that is needed to do so. A transition coding circuit is coupled between a data source circuit and the communication conductor, for driving the communication conductor in a first state in pulses in response to transitions in the logic signal and in a second state outside the pulses. The level that is used for indicating no change is selected so the current that needs to be supplied by the receiver is smaller when no change is signalled than when a change is signalled. Preferably only a nearly zero quiescent current is needed when there is no change.

摘要： An integrated memory includes a sense amplifier which has a parallel connection of a first and a second current branch, each current branch including channels of a control transistor and a load transistor which are coupled via a junction point, the junction points in each current branch being cross-wise coupled to the gates of the load transistors in the other current branch, and the junction points constituting outputs of the sense amplifier. The control and load transistors are of the same conductivity type, with each load transistor being connected in a source-follower configuration with its associated control transistor. As a result, the control transistors will be operative in the saturation region at all times and can be driven to full output, so that an integrated memory incorporating the invention is faster.

摘要： A current amplifier has an input terminal (1) for receiving an input current and an output terminal (2) for supplying an output current. A first transistor (T.sub.1) has a base-emitter junction coupled to the input terminal and a second transistor (T.sub.2) has a collector coupled to the output terminal and an emitter arranged in series with a voltage source (4). The series arrangement of the voltage source and the base-emitter junction of the second transistor is arranged in parallel with the base-emitter junction of the first transistor. The first transistor is of the NPN conductivity type and the second transistor is of the PNP conductivity type. The low internal series resistance of the NPN transistor T.sub.1 develops a relatively small voltage drop so that the attenuated output current (I.sub.out) is a linear function of the input current over a wide range of input currents. This results in a current-sourcing attenuating current mirror having a far better linearity than a current amplifier in which the first and second transistors are both of the PNP conductivity type.
