Claim Text:
1. A circuit system comprising: a differentiator configured to receive an input signal and to provide a derivative of the input signal; and a quantizer coupled to the differentiator, configured to receive the derivative of the input signal and to sample the derivative of the input signal when the derivative of the input signal crosses one of a plurality of quantization thresholds to provide a quantized derivative of the input signal; and a continuous time digital signal processing block coupled to the quantizer, configured to receive the quantized derivative of the input signal and process the quantized derivative of the input signal to provide a derivative of an output signal; and an integrator coupled to the continuous time signal processing block, configured to receive the derivative of the output signal and to integrate the derivative of the output signal to provide the output signal.
