Abstract
A high-speed voltage shifter/amplifier, a sigma delta modulator having a high-speed voltage shifter/amplifier and method for performing an amplification/a voltage shift to an analog signal. The voltage shifter/amplifier comprising a capacitor and an isolator; the isolator is coupled to the capacitor. The capacitor is adapted to receive a control signal, to be charged by an input signal, and to provide an output signal. The capacitor has a capacitance that is responsive to a level of the control signal, and a change in the capacitance of the capacitor forces a change in a level of the output signal; and the isolator is adapted to electrically isolate the capacitor when the capacitance is changed.
