ABSTRACT:
A constant current source circuit includes a single differential amplifier having both voltage and temperature stabilization circuits. The voltage and temperature stabilization circuits operate on a feedback principle, each receiving an input from the differential amplifier, and each in turn providing a signal back to the differential amplifier to provide the desired stabilization. The resulting circuit is particularly adapted for use in battery-powered equipment, where substantial variations in both temperature and operating voltage are likely to occur.
