Astable multivibrator

A simple astable multivibrator circuit provides the pulsed voltage for the stirring coil. It operates at a pulse frequency of about 2 cycles per sec. from voltage taken from the tungsten lamp power supply.

Several circuits containing standard threshold switches were chosen to test the feasibility of operating amorphous semiconductor devices in a radiation environment (Ovshinsky et al (1968) Shanks et al (1970a)). Among these circuits were a relaxation oscillator, an astable multivibrator, an AND/OR gate with complementary outputs and a J-K flip-flop. All circuits...
