Gate control circuit for high bandwidth switch design

An analog switch configuration includes a gate control circuit coupled between an input of a switch and a gate of the switch. The gate control circuit passes voltage changes on the input of the switch to the gate of the switch to decrease the influence the inherent gate to input capacitance has on t...

Summary:An analog switch configuration includes a gate control circuit coupled between an input of a switch and a gate of the switch. The gate control circuit passes voltage changes on the input of the switch to the gate of the switch to decrease the influence the inherent gate to input capacitance has on the bandwidth of the switch. By reducing the change in voltage across the inherent capacitance, the current through the capacitance in decreased as well as its influence on the bandwidth of the configuration.
