ABSTRACT:
A linear output amplifier for a charge coupled device arrangement in which the amplifier has a field effect switching transistor serially connected to a load element, the connection point between the transistor and the load element being the output of the amplifier and the gate terminal of the transistor being the input of the amplifier. The input of the amplifier is connected to the charge coupled device arrangement by either connecting it to the output diffusion zone of the same or by connecting it to a control electrode of the charge coupled device arrangement. Between the output of the amplifier and the input of the amplifier an additional transistor is provided with the aid of which the input can be connected to the output. Preferably, the load element is a field effect transistor and the load resistance which it provides can be varied by connecting a voltage source of desired amplitude to the gate terminal thereof.
