Abstract

A linear solid state servo amplifier operated from a low voltage source and which develops a voltage across the servo motor equal to the source voltage diminished only by the saturation voltages of two of its output transistors has a bridge output stage of complementary transistors and a bridge driver stage of complementary Darlington transistors having as its load a preselected resistor.
