Abstract:
A successive approximation register, SAR, analog-to-digital converter, ADC, ( 400 ) is described. The SAR ADC ( 400 ) includes: an analog input signal ( 410 ); an ADC core ( 414 ) configured to receive the analog input signal ( 410 ) and comprising: a digital to analog converter, DAC ( 430 ) located in a feedback path; and a SAR controller ( 418 ) configured to control an operation of the DAC ( 430 ), wherein the DAC ( 430 ) comprises a number of DAC cells, arranged to convert a digital code from the SAR controller ( 418 ) to an analog form; a digital signal reconstruction circuit ( 450 ) configured to convert the digital codes from the SAR controller ( 418 ) to a binary form; and an output coupled to the digital signal reconstruction circuit ( 450 ) and configured to provide a digital data output ( 460 ). The DAC ( 430 ) is configurable to support at least two mapping modes, including a small signal mapping mode of operation; and the SAR controller ( 418 ) is configured to identify when the received analog signal is a small signal level, and in response thereto re-configure the DAC ( 430 ) and the digital signal reconstruction circuit ( 450 ) to implement a small signal mapping mode of operation.

Claim (Index 19):
The method of  claim 11 , further comprising identifying, by the SAR controller, that the received analog signal is a small signal level, and in response thereto configuring the DAC to skip a portion of a conversion operation of the sampled analog signal.
