Charge cancellation circuit for switched capacitor applications |
摘要 |
A switched capacitor circuit, including a load-capacitor, and a charging switch which is coupled to apply a potential to the load-capacitor. The circuit further includes a compensating-capacitor and switching circuitry which is coupled to the charging switch and the compensating-capacitor and which is switchable. The switching is arranged to transfer to the compensating-capacitor an injection error charge produced by the charging switch, and then to isolate the injection error charge on the compensating-capacitor from the load-capacitor.
