ABSTRACT:
An improved amplifier with controlled hysteresis and an extremely low current drain capable of operating over a sufficiently large input voltage dynamic range is provided. Two circuits comprising a transistor and a diode are coupled between a differential amplifier and two cross-coupled current mirrors for preventing transistor saturation in the current mirrors.
