In view of the topology of the hybrid active power filter with injectioncircuit, analysis its principle in detail, as well as choice the desirable resonance frequency.
The sample and hold circuit is employed by the bottom plate sampling technique, which could not only cancel the charge injection error but also eliminate the effect of clock feed-through.
