摘要： A high speed, low-power transresistance amplifier incorporating a threshold-biased, current-mode feedback inverter. Starvation transistors are connected between the inverter's power supply terminals and the supply. Capacitors are connected between the power supply and the nodes at which the starvation transistors are connected to the inverter to bypass the starvation transistors and decrease the AC impedance of the nodes, as seen by the inverter. A resistive network connected between the starvation transistors and a bias voltage supply decreases the effective DC impedance of the nodes.

摘要： An insulated Gate Field Effect Transistor (IGFET) static inverter having an improved load line characteristic is disclosed. The inverter comprises an enhancement mode IGFET active device in a first portion of a semiconductor substrate, having its drain connected to an output node, its source connected to a source potential and its gate connected to an input signal source. The first portion of the substrate is connected to a first substrate potential. A depletion mode IGFET load device is located in a second portion of the semiconductor substrate which is electrically isolated from the first portion. The depletion mode load device has its drain connected to a drain potential and its source, gate and the second portion of the semiconductor substrate all connected to the output node. In this manner, the rise in the source-to-substrate voltage bias during the turn-off transition is eliminated in the depletion mode load device, providing an improved load current characteristic for the inverter. Alternate embodiments are disclosed directed to an all N-channel inverter, an all P-channel inverter, and a complementary inverter consisting of a P-channel load device and an N-channel active device.

摘要： A signal voltage (E) based upon a supply voltage must be converted to a signal voltage (A) with ground reference so as to enable further processing in a logic circuit. A simple level converter comprises a series connection of a MOSFET (T1) connected to the supply voltage; the MOSFET also comprises a resistor (T2). The source terminal of the MOSFET (T1) is located at the potential of the supply voltage. The voltage to be converted is applied between the gate terminal and the source terminal, and the converted voltage occurs at the resistor (T2). The two voltages are each limited by one Zener diode (D2, D1).

摘要： An output stage circuit includes a first P-type metal-oxide-semiconductor transistor, a second P-type metal-oxide-semiconductor transistor, an N-type metal-oxide-semiconductor transistor, and a current source. A voltage of a third terminal of the first P-type metal-oxide-semiconductor transistor is a first voltage minus a voltage drop between a first terminal and a second terminal of the first P-type metal-oxide-semiconductor transistor. The N-type metal-oxide-semiconductor transistor is coupled between the third terminal of the first P-type metal-oxide-semiconductor transistor and the current source. A second terminal of the second P-type metal-oxide-semiconductor transistor is coupled to the third terminal of the first P-type metal-oxide-semiconductor transistor. When a second terminal of the N-type metal-oxide-semiconductor transistor receives a kick signal, a driving current flowing through the second P-type metal-oxide-semiconductor transistor is relevant to the voltage of the third terminal of the first P-type metal-oxide-semiconductor transistor.

摘要： An off-chip driver circuit including an enhancement PFET, a depletion PFET, a depletion NFET and an enhancement NFET connected in series. The large enhancement PFET and large enhancement NFET turn off the OCD in tri-state and to turn off the unused half of the OCD to prevent overlap current when driving a ‘0’ or a ‘1’. A first gate signal is applied to the gate of the enhancement PFET and a second gate signal is applied to the enhancement NFET. A fixed voltage is connected to the gate of the depletion NFET and ground to gate of the depletion PFET. An output signal is obtained from a node between the depletion PFET and depletion NFET devices. In another embodiment, a reflection/overshoot sensor 60 is added. The output of sensor is connected to the body of a depletion PFET and an NFET. The feedback from sensor is such that the threshold voltage of the depletion devices are made more positive if the sensor detects that the output is being over-driven. A more positive threshold voltage will reduce the driver's IDS, but leaves the device in the linear mode.
