Abstract:
1. A bootstrapped switch circuit coupled to a timing circuit that provides one or more clock signals, and having an input terminal and an output terminal, comprising: a switch having a first terminal coupled to the input terminal, a second terminal coupled to the output terminal, and a control terminal; a charge pump, including a storage capacitor connected to either the first terminal or the second terminal of the switch and one or more capacitors coupled to the clock signals, wherein the charge pump is isolated from the timing circuit via the one or more capacitors of the charge pump and wherein the charge pump generates an output voltage across the storage capacitor; and a logic circuit, including one or more capacitors coupled to the clock signals, wherein the logic circuit is isolated from the timing control circuit via the one or more capacitors of the logic circuit and wherein the logic circuit provides a control signal to the control terminal of the switch that is derived from the output voltage across the storage capacitor.
