  • PULSE MODULATED CHARGE PUMP CIRCUIT
    Publication number: 20100148840
    Abstract: A circuit for increasing a gate voltage of a transmission gate in a high-speed switch to a level higher than a level of a supply voltage is provided. The circuit includes an oscillator generating a clock signal and a charge pump circuit operatively coupled to the oscillator. The charge pump circuit receives the supply voltage and the clock signal as inputs, and outputs the gate voltage. The circuit also includes a comparator circuit coupled to the oscillator circuit and the charge pump circuit and a pulse signal generator circuit operatively coupled to the oscillator, the pulse signal generator circuit generating a pulse signal which enables the oscillator.
