Abstract
A switch comprising: a channel path comprising first and second MOS transistors with common source and gate terminals and drain terminals defining first and second terminals of the channel path; and control circuitry comprising: a third MOS transistor comprising: a gate coupled to the common source terminal; a source coupled to the common gate terminal by a resistor; and a drain coupled to a first reference terminal; a first current source coupled between the first reference terminal and the common gate terminal for providing a first current; a second current source coupled between the source terminal of the third MOS transistor and a second reference terminal for providing a second current greater than the first current; and a first switching arrangement configured to selectively enable and disable the first current source; and a second switching arrangement configured to selectively couple the common source terminal to the second reference terminal.
