Abstract

A switched capacitor buffer operating by the push-pull method is taught. The buffer may include a pull-up device and a pull-down device. A switched capacitor circuit may be used to control the pull-up device and the pull-down device to achieve accurate push-pull operation. According to some embodiments, the switched capacitor buffer displays an optimal combination of design simplicity, low power consumption and high-frequency response.
