    摘要： A class-AB push-pull drive circuit comprises a P channel MOS transistor having a source connected with a DC power source, a drain connected with an output terminal and a control electrode coupled with an input terminal through a voltage-to-current converter and a current-to-voltage converter and an N channel MOS transistor having a source grounded, a drain connected with the output terminal and a control electrode coupled with the input terminal. Conversion characteristics of the converters are so set that a potential difference between the control electrodes of the transistors is kept constant independently of the voltage of an input signal. Thus, the rise and fall of voltage at the output terminal during the conducting state of respective transistors is decreased. In addition, a push-pull drive operation by the transistors can be achieved in accordance with the input signal.

    摘要： A constant-voltage circuit includes a transistor (Q3) for output control connected between a source potential and a ground potential and a divider circuit (R1, R2, D2, D3) which are connected in series. The dividing point of the divider circuit connected between the emitter of the transistor (Q3) and the ground potential serves as an output terminal to be supplied with a predetermined voltage by the emitter of the transistor (Q3), so that a constant voltage appears at the output terminal. Connection between the base and the collector of the transistor (Q3) is so improved that the emitter voltage is not changed following a change in the source voltage. More specifically, the transistor (Q3) is connected in such a manner that the collector-to-emitter voltage is continuously clamped by the base-to-emitter voltage of the transistor (Q3), so that the transistor (Q3) is not subjected to a base width modulation effect and thus the emitter potential is not changed following the change in the source voltage.
