Abstract :
A power amplifier designed for use as a biological stimulator is described. It is driven by a dc voltage or a pulse generator with an amplitude of 50 volts. The output power of up to 250 volts and 100 ma is precisely controlled. The rise time is less than 5 ¿sec. A dual-channel version whose outputs may be independently controlled and mixed is also described. The circuit for the +400 volts and ¿300 volts regulated power supplies is shown.
