Abstract: A device for converting analog to digital is disclosed. The device includes a dual mode converter and a control unit. The dual mode converter has a coarse mode and a fine mode. The dual mode converter is configured to receive an input signal and convert the input signal to a digital output having a selected resolution. The control unit is coupled to the dual mode converter and is configured to operate the converter in the coarse mode until a coarse approximation is obtained and to operate the converter in the fine mode until a fine approximation is obtained having the selected resolution. The fine mode includes multi-bit incremental tracking.
