ABSTRACT:
An ADC implemented according to an aspect of the present invention contains a non-zero bit stage followed by a zero-bit stage. The non-zero bit stage generates a sub-code, which is used in generating a digital code corresponding to an input analog signal, and the zero-bit stage does not provide any such sub-codes. Such a feature may be attained by using a gain amplifier provided according to another aspect of the present invention. The gain amplifier contains a main-amplifier which operates as a zero bit stage, and is also used by the non-zero bit stage. The same capacitance value may be maintained between the input terminal and output terminal of the main-amplifier to implement the zero bit stage, which enables the main-amplifier to be implemented with a low gain.
