ABSTRACT:
An analog-to-digital converter has an input for receiving analog signals, a quantizer for producing a digital output of the converter, a first combining node for combining the analog input with a first feedback signal derived from the digital output and producing a first combined signal, and filter circuitry for filtering the first combined signal. The filter circuitry includes at least one filter circuit stage which is not connected to a phase-modifying resistance, and a second combining node for combining an output from the at least one filter circuit stage with a second feedback signal derived from the digital output, and produces a signal for input to the quantizer.
