Abstract
Techniques for designing a high performance analog switch for use in electronic circuit applications. In one aspect, a variable bulk voltage generation module is provided to vary the bulk voltage of a transistor in the switch, such that the threshold voltage of the transistor is reduced during the on state. In another aspect, a pulling transistor is provided to pull a middle node of the switch to a DC voltage during the off state to further increase the isolation provided by the switch.
