ABSTRACT:
An input stage includes a plurality of arrays of autozero amplifiers arranged in series in each array, wherein each autozero amplifier receives an output of a preceding autozero amplifier, wherein a first autozero amplifier in each array amplifiers receives an input signal and a corresponding reference voltage at its inputs, and wherein at least one of the autozero amplifiers includes a circuit that receives the signal corresponding to the output signal, the circuit substantially passing the signal corresponding to the output signal and the reference voltages to the amplifiers during the clock phase φ2and substantially rejecting the signal corresponding to the output signal during the clock phase φ1.
