The utility model discloses an adc, adc can include integrator, gate ring oscillator, thick counter, looks bit status register, counter register and logic circuit. Gate ring oscillator can export phase place status signal consecutively looks bit status register. Phase place status signal includes a plurality of phase place nodes, each person in a plurality of phase place nodes is via a plurality of delay -level transmission signal and form. Can with one of phase place node offers thick counter. Looks bit status register with up -to -date corresponding phase place state and thick counter outputcan be saved respectively to the counter register. Corresponding to the steerable phase place state of saving of simulated image incoming signal's control signal and the thick counter output that saves to logic circuit's output. Logic circuit can based on looks bit status register with the counter register output generates simulated image incoming signal's digital edition.
