Abstract
A signal switching circuit in which distortion caused by non-linearity of a signal path between a control electrode of an output transistor and a common junction output terminal is eliminated. The switching circuit includes plural amplifiers with outputs of the amplifiers being coupled to a common junction point and with a control signal coupled to each amplifier for enabling or disabling the amplifier. A by-pass impedance element having a linear voltage-current characteristic is coupled between the control electrode of each transistor and the common output junction point.
