Time domain comparer with low power dissipation feedback control structure

The invention relates to a time domain comparer with a low power dissipation feedback control structure, belonging to the technical field of analog-digital converters. The time domain comparer is characterized by comprising a feedback control circuit with input voltage, a non-conjunction gate switching circuit and a output circuit which are sequentially connected in series, at the control of a clock signal, the level of output voltage is controlled by the feedback control circuit through a capacitive charge-discharge method at the regulation and control of a feedback output signal according to the relative size of two full differential input signals, and the purpose that quiescent power dissipation is reduced by numerical control logic at the normal running condition of the analog-digital converter is achieved.
