Abstract:
Methods and apparatus for providing bandpass analog to digital conversion (ADC) in RF receiver circuitry of a wireless-communication device. The bandpass ADC includes first noise-shaping successive approximation register (NS-SAR) circuitry arranged in a first path and second NS-SAR circuitry arranged in a second path parallel to the first path, wherein the first and second NS-SAR circuitries are configured to alternately sample an analog input voltage at a particular sampling rate and to output a digital voltage at the particular sampling rate.
