1. A two-stage gate driver circuit for driving a junction field effect transistor having a gate, a source, and a drain, the two-stage gate driver circuit comprising:
an input for receiving an input control pulse signal with which switching of the junction field effect transistor is to be synchronized; a first on circuit that provides, in response to the input control pulse signal, a forward gate current to the junction field effect transistor at least during a conduction stage of the junction field effect transistor; a second turn-on circuit that provides, in response to the input control pulse signal, a current to charge the gate during at least part of a turn-on stage of the junction field effect transistor, wherein the current to charge the gate is relatively higher than the forward gate current; and a pull-down circuit, wherein the first on circuit, the second turn-on circuit and the pull-down circuit are electrically coupled between the input and the gate of the junction field effect transistor in parallel, and wherein the current to charge the gate during at least part of a turn-on stage of the junction field effect transistor is a pulse that terminates while the forward gate current is provided by the first on circuit. |
