Abstract
An antisaturation circuit for an integrated PNP transistor, having a generic current generator in the base branch of the bias circuit capable of limiting the maximum base current, comprises two NPN transistors, a diode and a voltage divider formed by two resistors, and permits to limit the base current of the PNP transistor below the maximum value, set by the current generator, every time the voltage across the base-collector junction of the PNP transistor exceeds a certain preset value thus preventing saturation or limiting it.
