The invention relates to an analog to digital converter (ADC) circuit. The ADC circuit is characterized in that: an input voltage is converted into an input current by a voltage-current conversion circuit; a feedback current generated by a feedback current circuit is converged with the input ...
An analog-to-digital conversion circuit includes a first comparator, a second comparator and a counter circuit. The first comparator compares an analog signal with a ramp signal. The second comparator compares the analog signal with the ramp signal plus a predetermined offset. When a signal level...
