PUSH-PULL POWER AMPLIFIER |
摘要 |
FIELD: low-frequency power amplifiers that may be used for hearing aids. SUBSTANCE: device has two preamplifiers and output stage incorporating two n-p-n output transistors and two switches built around p- n-p transistors. Power amplifier output passing lower current from collector of output transistor is connected by means of switches to power bus. Preamplifiers function to amplify antiphase variables of output voltage components and to compensate for DC components of output current. EFFECT: twice as high saving of current fed from power supply. 1 dwga
