ABSTRACT:
According to an aspect of present invention, a quantizer is provided with reduced power consumption and area. Such a feature is attained by providing the input signal and a reference signal on input terminals of a pre-amplifier, and coupling the differential output terminals of the pre-amplifier to the gate terminal of respective transistors. The drain/source currents of the transistors are provided to a current latch, which generates the comparison result. The latches and transistors are replicated conveniently to interpolate additional reference values. The width to length (W/L) of the channels in each replicated set are set to different values to cause the reference signal to be at corresponding strength.
