Solid state zero-bias bilateral switch
Circuit switches a plus or minus 2.5 volt peak, dc to 300 kHz input to an operational amplifier. Featured is a bilateral transistor which draws a saturation current of equal amplitude and opposite polarity to the saturation current of the bilateral transistor, cancelling the dc bias effect at the output.
