Abstract
Methods are disclosed for performing analog to digital signal conversion in shorter time and/or with less power consumption. A predictive guess is supplied as a digital first signal. The digital first signal is converted (D/A) to a counterpart, analog guess signal. A comparison is made between the analog guess signal and a received, analog input sample signal. The result of the comparison is used to improve on the initially supplied guess in a next cycle. Fewer cycles and less power is consumed if the initial guess is within a certain range of the actual magnitude of the analog input sample signal.
