Abstract
The invention provides a majority voting circuit, which is characterized in that a control signal output end output by a comparison circuit is respectively connected with an input end of an internal circulation circuit, a control signal input end of a threshold detection circuit and a control signal input end of a voting circuit, so that the internal circulation circuit can send a received control signal to the voting circuit; the first clock signal and the second clock signal are converted into the corresponding first clock signal and the second clock signal to be output, and the second clock signal is used as a bias voltage to be input to the bias voltage input end of the threshold detection circuit, so that the threshold detection circuit can judge whether to start the voting circuit according to the received bias voltage and the first clock signal; therefore, the bias voltage can be provided for the threshold detection circuit without adopting an additional analog circuit, the detection of the amplitude of the input signal is realized, and the area and the manufacturing cost of the majority voting circuit are further reduced.
