Abstract:
A hybrid counter generates a multi-bit hybrid counter value. The hybrid counter includes two or more asynchronous counters, each configured to generate a subset of the bits of the multi-bit hybrid counter value. The asynchronous counters are interconnected by a logic gate and a clock gating circuit. The logic gate generates an asynchronous logic value based on the bits generated by the previous asynchronous counters. The clock gating circuit re-times the asynchronous logic value to generate a synchronous logic value that is used to toggle the next asynchronous counter. The hybrid counter functions more accurately than conventional asynchronous counters and with less power than conventional synchronous counters.
