Abstract
One of the input and output terminals of a current amplifier is coupled via a threshold conduction device to a drive circuit input terminal and the other of the input and output terminals is coupled via the conduction path of an output transistor to an output terminal of the drive circuit. A further amplifier, coupled to the threshold conduction device, provides a low impedance drive signal for the control electrode of the output transistor for biasing the output transistor to produce an output current proportional to an input current applied to the drive circuit input terminal and for enhancing the transient recovery time of the drive circuit for abrupt changes in output voltage at the output terminal.
