Abstract
A sampling capacitor structure, which includes a Faraday Shield that can be switched between various nodes. In a switched capacitor circuit, this sampling capacitor structure allows for differential charging of the sampling capacitor while minimizing the effects of any parasitic stray capacitor. Furthermore, with appropriate switching of the Faraday Shield, once the differential charge sampling circuit samples the differential signal, this sampled differential charge can then be transferred to a downstream single-ended circuit, such as an integrator, without any loss of signal.
