ABSTRACT:
A low power, astable multivibrator which operates on supply voltages as low as 1.5 volts and is suitable for controlling the application of power to power consuming electrical devices in battery-powered applications is disclosed. A transistor circuit which utilizes relatively large resistance values and positive feedback is presented. Resistance values are sufficiently large to bias transistors so that operation of the transistors in their saturation regions would be prevented without the application of the positive feedback.
