ABSTRACT:
An SAR analog-to-digital converter performs bit decisions in each of a plurality of clock cycles. A sense circuit monitors signals input to a latch within a comparator of the ADC and, when the signals are sufficient to establish a bit decision, the sense circuit terminates a currently active clock cycle causes a bit decision to occur in advance of a normal expiration of the clock cycle. If the signals are insufficient to establish a bit decision prior to a default expiration time of the clock cycle, the clock cycle concludes at the default expiration time.
