Title: Output amplifier
Inventor: HIGUCHI SHIGEMITSU
IPC: H03F1/02
Filed: 1978-03-15
Abstract: PURPOSE:To avoide the deterioration of the switching distortion without increasing the voltage applied between the collector and emitter of the output transistor at the delivery time of the high-band frequency in case the power voltage is switched in accordance with the output level of the signal to actuate the output transistor near the maximum output. CONSTITUTION:When the positive signal voltage emerging at output terminal 3 is lower than the voltage of power source 9, output transistor 6 is cut off in the reverse bias state. And the current flows to speaker 4 from source 9 via output transistor 5. While in case the positive signal voltage emerging at terminal 3 is higher than source 9, transistor 6 features the forward bias with diode 17 set backward bias. As a result, the current is supplied to speaker 4 from power source 10 via transistor 6 and 5. Then capacitor 19 and 20 are connected between the base and the emitter as well as between the base and the collector of transistor 6 respectively. And the B-class action is secured only by source 10 at the high frequency band, thus preventing the distortion caused by switching of the power source. The operation is same with the negative signal, too.
