Introduction

Shiva Prasad Kotagiri is a notable inventor based in Campbell, California. He has made significant contributions to the field of technology, particularly in the area of clock and data recovery systems. With a total of five patents to his name, his work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is titled "Clock recovery using quantized phase error samples using jitter frequency-dependent quantization thresholds and loop gains." This invention involves a clock and data recovery device that includes a phase detector, a quantizer, and a loop filter. The phase detector produces phase error samples that represent the phase difference between a phase-adjusted clock and an input data signal. The quantizer, which is responsive to high and low threshold values, generates tri-valued quantized phase error samples. The loop filter then controls the phase-controlled clock by filtering either the quantized or phase error samples. Additionally, a frequency detector determines the frequency of jitter in the input data signal, utilizing a look-up table to provide the necessary threshold values.

Another significant patent is "Adaptation of gain of baseline wander signal." This invention pertains to a receiver in a serializer/deserializer (SerDes) system. It includes a coupling capacitor that receives a serial input signal and outputs a capacitance signal. An equalizer processes this signal, while a running disparity generator and a low-pass filter work together to output the baseline wander gain.
