ABSTRACT:
In general, in one aspect, the disclosure describes a hybrid analog-to-digital converter. The hybrid converter comprises a successive approximation analog-to-digital converter for receiving an analog input signal and generating at least one bit of a digital output signal and a cyclic analog-to-digital converter coupled to the analog input signal and the successive approximation analog-to-digital converter for generating at least one additional bit of the digital output signal.
