ABSTRACT:
Backward-mapping switched capacitor (SC) differentiators for MOS technology integrated circuit implementation, as well as forward mapping (FM) and bilinear-mapping (BIM) SC differentiators, are disclosed. The SC differentiator is employed in filters either alone or in combination with SC integrators. The filters include biquads, ladder filters, FIR filters, IIR filters and N-path filters.
A fully differential operational amplifier with high and symmetrical driving capability is also described.
