Abstract
A method for controlling a switch based on transistors is disclosed. A switching circuit for switching a signal from an input port to an output port thereof is provided. A shunting circuit for switchably shunting the signal from the input port to ground is also provided. A control signal is generated for biasing a control port of the shunting circuit and an approximately complimentary control signal is generated for biasing of the switching circuit to either shunt a signal received at the input port or to switch the signal to the output port. A further bias signal for biasing a port within the switching circuit along the signal path between the input port and the output port is also provided.
