Abstract

PURPOSE: To reduce current consumption, by inserting transistors (TR) in Darlington connection, constant voltage diode, capacitors and resistors ti a class B PP circuit as specified consisting of a driver and output TRs.
CONSTITUTION: TRs Q3, Q4 are in Darlington connection, a constant voltage diode D1 is connected between the bases of TRs Q3 and Q2, in series to a resistor R1 and in parallel with a capacitor C1, and a diode D2 is inserted between the base of the TRQ3 and power supplies V1, V2. The power supply V2 is connected to the collector of the TRs Q3 and Q4, and a diode D3 is connected between the emitter and the power supplies V1, V2. This is made the same to a negative half wave, and a resistor R2 is connected between the bases of the TRs 2, 6. In this case, among an output E0, zener voltage Vz, forward voltage Vf of a diode D3, through the relation of E0+VBE2+V2 and V1-Vf+VBE4+VBE3, charge/discharge of the capacitor C1 is used, allowing to prevent the application of greater reverse voltage between the base and the emitter of the TRs Q3, Q4 at negative half period. Thus, ±V1, ±V2 are made greater to obtain an large output amplifier having good current efficiency.
