Title: Power amplifier
Inventor: HITAI TAKASHI
IPC: H03F3/30
Filed: 1982-08-31
Abstract: PURPOSE:To improve the utilizing factor of power supply voltage and to reduce remarkably an idle current, by connecting two outputs of an amplifier from which an inverting and a non-inverting signal are outputted in common respectively to a base and an emitter of a complementary output transistor (TR) and driving output TRs with the collector output. CONSTITUTION:When a signal is applied to an input signal terminal Ti, a voltage of opposite phase is outputted at points (a) and (b) with amplifiers A1, A2. Since TRs5-TR8 form a class B power amplifier taking points (a), (b) as inverting input terminals, they constitute a power amplifier having a voltage gain determined with negative impedance elements Z1, Z2 as a whole. Since the output TRs7,8 form a common emitter amplifier circuit, they are driven to a base current determined with a control resistor R and used to the collector-emitter saturating point. Further, when no signal is give to the input signal termial Ti, since no potential difference is provided between the points (a) and (b), the TR5-TR8 are all nonconductive and the idling current is only the idling current at no input signal of the amplifiers A1, A2.
