ABSTRACT:
A differential cascode voltage switch circuit includes a plurality of devices wherein a portion of the plurality of devices have a low threshold voltage and a remainder of the plurality devices have a regular threshold voltage for providing a performance gain without a substantial increase in standby power wherein at least one device has regular threshold voltage between a supply voltage and a ground. A method of producing a multi-threshold voltage circuit includes the steps of defining between a supply voltage node and ground at least one regular threshold voltage device for producing a high resistance to reduce current leakage and defining low threshold voltage devices within the circuit for reducing leakage current.
