Abstract: A slewing mitigation technique is presented where just the right amount of charge is provided at the switching instant to a switch capacitor circuit so that operational transconductance amplifier (OTA) does not need to provide high peak current. This eliminates slewing altogether and allows using OTAs with less static current for the same settling accuracy.

Abstract: A signal scaling circuit for accurately reducing the effective amplitude of an input signal by a rational factor N/M, where N and M are integers and N<M, is disclosed. An input, reference, bias and output node as well as control circuitry are selectively coupled to M switched capacitor circuits such that N/M scaling may be achieved. Cooperation between the M switched capacitor circuits and the control circuitry divides the M switched capacitors circuits into subsets of N and M-N switched capacitors, respectively. Each subset is then selectively coupled to an input, reference and/or bias signal to produce an output signal having as one of its components an N/M portion of the input signal. Error reduction in the scaled signal is achieved by shuffling the switched capacitor circuits populating each subset after selected time intervals.
