Abstract
Embodiments of the invention include an oversampling Analog to Digital Converter that uses uneven non-overlapping clock phases to reduce switched capacitor circuit power consumption. A return-to-zero sub phase of one of the clock phases may also be used for feedback reference capacitors. A delay lock loop may be combined with the non-overlapping clock phase generator to control accurate timing.
Claims2
An analog-to-digital modulator, comprising:
- a switched-capacitor loop filter, including:
- integrators operable in a charging phase and a dumping phase, in which at least some of the integrators are decoupled from the remaining integrators during the dumping phase.
Dependencies are inferred from the claim text.
