Abstract
A circuit for increasing the slew rate of linear amplifier circuits. The circuit comprises two NPN and PNP transistor pairs arranged so that when the voltage level difference between the amplifier output and input voltage exceeds the base to emitter voltage of such transistors, the circuit is activated. The circuit provides a current proportional to such voltage difference in order to speed up the charging or discharging of the slew rate determining capacitance.
