Abstract
The present invention discloses an analog-to-digital conversion circuit having remained time measuring mechanism is provided. A digital-to-analog conversion (DAC) circuit samples input voltages to generate output voltages. A comparator compares the output voltages to generate a comparison result. A control circuit switches a configuration of the DAC circuit by using a digital code according to the comparison result. A comparison determining circuit sets a stage indication signal at a finished state after the comparison result is generated. A comparison stage counting circuit accumulates a termination number according to the stage indication signal to set a conversion indication signal at the finished state when the termination number reaches a predetermined number. A time accumulating circuit starts to accumulate a remained time when the conversion indication signal is at the finished state and finishes accumulation when a sampling indication signal is at a sampling state.
