Abstract

A cascoded switch system is disclosed. The cascoded switch system includes JFET and a MOSFET coupled in series between a drain terminal and a source terminal. The system further includes a drive circuit comprising a JFET driver configured to receive an input signal and to output a JFET-drive signal to a capacitor coupled in series with the gate of the JFET, a switch coupled between the gate of the JFET and the source terminal and configured to be responsive to the input signal, and a comparator to compare a JFET gate voltage against a threshold. The drive circuit further includes a MOSFET driver circuit to drive the MOSFET in a MOSFET on-state during an on-state of the input signal, and drive the MOSFET in one of a MOSFET off-state and the MOSFET on-state in response to a comparison signal from the comparator during an off-state of the input signal.
