| Abstract | The junction-field effect transistor has been improved technically, so it is appropriate in analog switching applications. In this paper, use of a junction FET as an analog switch is described. Feedthrough of current from the gate control voltage causes a noise at the output during the switching transient. Peak noise levels are given, and curves show how noise can be reduced at the expense of switching speed and bandwidth of signal. A series-shunt switch is used to increase the switching speed without increasing the peak noise. The shunt switch provides a similar feedthrough at the same time to provide cancellation. The peak noise observed from the series - shunt switch was as low as 5 mv at a 300 ns switching time, and compared to 180 mv without compensation at the same speed. |
