    摘要: The binary values of the data word to be converted in a widely used type of D/A converter are supplied to a series of stages in which binarily stepped currents are supplied to a common output or derived therefrom, or are conducted to a second common output. To control the current switch, each stage comprises a flipflop in which the binary value to be converted is stored. Integration processes are often used in the integration of analog circuits by means of which digital circuit components cannot be usefully realized, for example, in the IIL technology. In the flipflop comprising cross-coupled transistors, the emitters are connected to a reference voltage which lies between ground potential and the supply voltage so as to obtain a favorable conversion of the digital signals for triggering the current switch. This renders it possible to connect the collectors of the transistors of the flipflop directly to the bases of the current switch. In addition, the control of the flipflop is simplified thereby, and the delay time is shortened.

    摘要: A controlled power supply source is described, which has a parallel control member having a controllable semiconductor component whose load path is arranged between output terminals of the power supply source and whose control input is connected to an output of a control device, the control device having a reference input for supplying a reference voltage. The control device has a control amplifier which is fed from a current bank having at least one constant current source, an actual value input of said control amplifier receiving the voltage between the output terminals of the power supply source, and a nominal value input receiving the reference voltage from the reference input of the control device. An output of the control amplifier constitutes the output of the control device which further has a preliminary current stage which, dependent on the difference between the voltages at the actual value input and at the nominal value input of the control amplifier, applies a preliminary current to this control amplifier, which preliminary current is applied to the control input of the semiconductor component at least partly via the output of the control device. This provides the possibility of controlling high power supply voltages, and when the source is switched on, only a very short period of time is required to reach the linear operating range of the parallel control member.

    摘要: A circuit for testing the leakage resistance of a circuit point. Particularly in the case of circuits where safety is important, a circuit point, particularly an output terminal of an integrated circuit, should be tested for a leakage resistance relative to ground and/or a voltage to provide an early detection of an imminent failure condition. To this end, at least one test current is fed into the circuit point and the voltage at the circuit point is monitored by means of a comparator. When the leakage resistance decreases below a permissible value the voltage at the circuit point decreases, which can be detected by the comparator. For monitoring a leakage resistance relative to both poles two opposite test currents are applied and the comparator is constructed as a window comparator.
