Abstract
A sigma delta receiver achieves increased stability and noise reduction. The sigma delta receiver includes a first integrator stage, an isolation stage, a second integrator stage, and a quantization stage. The first integrator stage receives an analog radio frequency (RF) signal from an antenna and generates an analog baseband signal based on the analog RF signal. The isolation stage is coupled to an output of the first integrator stage. The isolation stage receives the analog baseband signal from the first integrator stage and amplifies the analog baseband signal. The second integrator stage is coupled to an output of the isolation stage to receive the analog baseband signal. The second integrator stage further amplifies the analog baseband signal. The quantization stage converts the analog baseband signal to a digital signal, and outputs the digital signal.
