Latest Patents

Yi Zhang's latest patents focus on digital techniques for excess loop delay compensation in continuous-time delta sigma modulators. The first patent describes a continuous-time delta sigma modulator that includes a quantizer, a buffer module, and a reference module. The quantizer features a comparator that updates a digital output each cycle of a clock signal based on a comparison of a reference potential with an input generated from an analog signal sample. The buffer module stores the digital output for a predetermined delay period and outputs it as a delayed digital output. This delay period is less than one cycle of the clock signal, allowing for efficient processing. The reference module selectively varies the reference potential based on the delayed digital output.

The second patent also addresses excess loop delay compensation in a continuous-time delta sigma modulator. This invention includes a quantizer with two comparators. The first comparator generates a digital output based on a comparison of a first reference potential with an input from an analog signal sample. The second comparator generates a second digital output based on a comparison of a second reference potential with the same input. The reference module varies the first and second reference potentials based on these digital outputs, enhancing the modulator's performance.
