Abstract
PURPOSE: To improve reliability by composing a modulated-signal amplifier of transistors by boosting a pulse-width-modulated signal by a pulse transformer after amplification by using a pulse amplifier.
CONSTITUTION: Pulse-width modulation is done by a sound signal and after its output is amplified by pulse amplifier 30, it is boosted by pulse transformer 31 to detect the boosting output by detection circuits 34 and 35. In this way, high out-of-phase outputs for driving transformerless PP amplifier 21 can be obtained. Therefore, amplification characteristics improve through the transformerless system and a transistor low in dielectric strength can be used for pulse amplifier 30. Consequently, the reliability can be improved and its miniaturization can be attained through transistor-implementation like this.
