Abstract
Circuits and methods for current recycling in signal buffers for switched capacitor circuits are described. A signal buffer may be coupled to an impedance element, such as a resistor, configured to provide a desired reference voltage to the switched capacitor circuit. In some embodiments, a portion of the power absorbed by the impedance element may be recycled to power one or more additional circuit. Such additional circuit(s) may include active elements. In some embodiments, the switched capacitor circuit is part of an analog-to-digital converter. In some embodiments, the additional circuit(s) are also part of the analog-to-digital converter.
