Abstract
An electronic switch that includes a signal path with a first terminal side of the signal path including cascoded transistors in the signal path. When the switch is in an off state, the gate of one of the cascoded transistors is biased at an intermediate voltage different from the voltage applied to the gate of the other of the cascoded transistors. In one embodiment, having the gate of one of the cascoded transistors biased at an intermediate voltage in an off state may reduce leakage current into a signal terminal of the switch. The electronic switch includes an injection shunting device (e.g. such as a transistor) connected to a node of the signal path. In one embodiment, the injection shunting device prevents the voltage of the node from reaching a specific voltage level due to leakage current when the switch is in an off state.
