    摘要： A complementary or quasi-complementary Class B transistor amplifier stage, the halves of which have their output circuits serially connected between relatively negative and relatively positive operating supply voltages to receive direct current and are operated in push-pull with each other for signal to supply a common load from the interconnection of their output circuits, has driver circuitry including a pair of field effect transistors operated in push-pull to supply respective halves of the Class B transistor amplifier. A p-channel field effect transistor with source electrode connected to the relatively positive operating supply voltage drives one half of the Class B transistor amplifier stage from its drain electrode, and an n-channel field effect transistor with source electrode connected to the relatively negative operating supply voltage drives the other half of the Class B transistor amplifier stage. The field effect transistors in the driver circuitry are enhancement-mode types permitting their gate electrodes to be connected together to receive input signal potential, avoiding the need for voltage translating circuitry to secure their push-pull operation.

    摘要： An output power stage which includes a PNP pull-up transistor and an n-channel FET push-down transistor, driven in phase opposition. This fully complementary stage provides an outstandingly improved power handling capability per semiconductor area occupied, together with a large output voltage swing, but does not require the use of externally connected discrete boot-strap components. The bipolar pull-up transistor can optionally be driven through an FET auxiliary stage, to minimize the power requirements of the preceding signal amplification stage.
