Abstract
A differential switch circuit includes: a first transistor having a first terminal coupled with a first input terminal, a second terminal coupled with a first output terminal, and a control terminal coupled with a switch signal receiving terminal; a second transistor having a first terminal coupled with a second input terminal, a second terminal coupled with a second output terminal, and a control terminal coupled with the switch signal receiving terminal; a central switch element positioned between the control terminals of the first and second transistors; and a switch element control circuit for controlling the central switch element based on a switch signal. When the switch signal turns on the first and second transistors, the switch element control circuit turns off the central switch element, and when the switch signal turns off the first and second transistors, the switch element control circuit turns on the central switch element.
