Abstract:
1. A successive approximation register analog-to-digital converter, comprising: a successive approximation register subcircuit, generating digital control bits in different cycles of a search scheme of the successive approximation register analog-to-digital converter; a digital-to-analog converter, comprising at least one set of capacitors and coupling an analog input of the successive approximation register analog-to-digital converter to the at least one set of capacitors and operating the at least one set of capacitors in accordance with the digital control bits, wherein each set of capacitors comprises p capacitors C a comparator, fed with an analog output transmitted from the digital-to-analog converter and generating a comparator output to be coupled to the successive approximation register subcircuit for generation of the digital control signals, wherein digital representation of the analog input of the successive approximation register analog-to-digital converter is approximated in the search scheme.
