Efficient charge transfer using a switched capacitor resistor |
摘要 |
The application of a non-zero voltage offset to rotating capacitors 1111 and 1112 permit the use of a single positive voltage supply. However, the precharging of the rotating capacitors 1111 and 1112 is power inefficient. A power efficient and low-noise precharging operation is realized through the sharing of the charge on a feedback capacitor 1075 and 1080 that is significantly larger than the rotating capacitors 1111. Once a precharging operation is complete, the charge on the feedback capacitor 1075 and 1080 is refreshed from its residual charge level (rather than zero charge level) to a desired charge level.
