| Zusammenfassung: | A method and apparatus for performing voltage-mode sample and hold functions while avoiding nonlinear charge injection. The method comprises oversampling an input signal and sampling an error signal, not the input signal directly, and through signal processing causing the error signal to be reduced to low amplitude. First order and higher order voltage-mode sample and hold circuitry embodiments are provided. |
