Abstract
A control circuit for signal transmission which comprises a plurality of field effect transistors (which will be hereinafter referred to as simply FETs) with gates of high resistance is disclosed. In this case, the sources and drains of the FETs are connected commonly and connected in parallel to a signal transmission path, their gates are supplied with different voltages, and the mutual conductances among the FETs are selected to be reduced gradually.
