摘要:
A dual-slope analog-to-digital converter and a comparison circuit for the dual-slope analog-to-digital converter. The dual-slope analog-to-digital converter includes a buffer, an integrator coupled to the buffer and the comparison circuit. The comparison circuit includes a differential output comparator and a comparison unit. The differential output comparator is coupled to the integrator and produces a pair of differential signals to output. The comparison unit receives the differential signals and chooses a signal, whose voltage is from a first level to a second level, from the differential signals to produce an output signal.
