Latest Patents

One of Siddharth Joshi's latest patents is for a predictive digital autoranging analog-to-digital converter. This apparatus includes a delta sigma modulator, where a first portion acts as a digital predictor and a second portion serves as an analog approximator. The output of the analog approximator is coupled with a quantizer, forming a digitizing loop that converts an analog input into a digital output. The digital predictor generates a prediction of the expected amplitude of the analog input based on the polarity of digital outputs from the quantizer. The quantizer adjusts the dynamic range of the digitizing loop by changing the quantization step size in response to the digital prediction.

Another notable patent is for a capacitive passive mixer baseband receiver with broadband harmonic rejection. This invention includes a receiver that generates in-phase and quadrature phase portions from an input signal. The harmonic rejection mixer, which comprises a plurality of capacitors with encoded capacitance values, reduces harmonics in the input signal. The apparatus also features switches that activate the capacitors, allowing for the application of predetermined capacitance values to the input signal based on the active capacitors.
