Research interests: Delta-Sigma ADC
The method to convert data from Analog to Digital form through Delta Sigma ADC is accurate because it uses the oversampling technique, decimation, noise shaping and filtering to reduce the quantization noise and obtain a high resolution with an improved SNR.

A method for reducing the complexity of a multi-bit DAC ina sigma-delta ADC. The DAC resolution can be made to be less than that of the quantizer by canceling truncation error present in multi-bit DA... Truncation errors are introduc...
Low-distortion delta-sigma topologies for MASH architectures
The first part of this two-part paper, published separately, discusses the quantization noise leakage problem caused in cascaded delta-sigma (MASH) ADCs by the imperfections of the first-stage analog circuitry.
