Latest Patents

Syed Imran Ahmed holds a patent for a delta-sigma modulator. This invention presents a system and method designed to achieve low power and/or low supply operation of a delta-sigma modulator. By leveraging the inherent virtual ground of the delta-sigma loop, the input to a low power integrator is minimized and largely independent of the input signal. This innovation results in improved linearity of the integrator and relaxed constraints on the supply for the first stage integrator. Additionally, the architecture allows for direct access to the quantization error of the feedback loop, enabling calibration of the modulator, reduction of quantization noise, and stabilization of the loop by compensating for excess loop delay. Low voltage common-mode feedback is also achieved using the techniques described in his patent.
