Abstract
An amplifier comprising means for eliminating direct-voltage transients on the amplifier output includes a controllable voltage source, coupled to the output or to a point in the amplifier such that the output voltage gradually increases to the steady-state value. The magnitude of the output voltage of said source, which conducts current in one direction only, can be controlled by means of a control voltage which is continuously variable during the turn-on period and which is applied to its input. The voltage source is connected to the amplifier so that as the amplifier output voltage rises, it is cut off by the resulting potential changes.
