Abstract

See full text

A bootstrapped switch circuit capable of operating at input signals from far below the negative supply rail to far beyond the positive supply rail may include (a) a switch having a first terminal coupled to an input terminal, a second terminal coupled to an output terminal, and a control terminal; (b) a charge pump coupled to one or more clock signals and isolated from a timing circuit via a first capacitor and a second capacitor, the charge pump generating an output voltage; and (c) a logic circuit coupled to one or more clock signals and isolated from the timing control circuit via a third capacitor and a fourth capacitor, wherein the logic circuit provides a control signal to the control terminal of the switch that is derived from the output voltage of the charge pump.
