Title: Innovations by Vivek K Sharma

Introduction

Vivek K Sharma is a notable inventor based in Olten, Switzerland. He holds 4 patents that showcase his contributions to technology and engineering. His work primarily focuses on enhancing electronic systems and improving their efficiency.

Latest Patents

One of his latest inventions is the phase rotator apparatus. This apparatus features phase interpolation and transimpedance amplifier (TIA) stages. It effectively separates gain and bandwidth as degrees of design freedom, which facilitates a reduction in power consumption while enabling higher speed data transmission and reception. The phase interpolation stage combines four phases of an incoming signal using weighting currents and current-source loads. This produces a phase-shifted current-based signal that the TIA stage receives as input. The TIA stage then converts this signal into a voltage-based signal. Additionally, the quiescent operating voltage of the stage outputs can be maintained with common mode feedback circuits and injector currents.

Another significant patent is the arrangement and method for temperature compensation for resistance. This invention involves a resistance with a controllable resistance value, which is compared with a reference resistance in the form of a switched capacitor. A comparator assesses the two resistance values and uses an error signal to actuate the controllable resistance. This process results in a thermally stable resistance, which can be particularly beneficial in transimpedance amplifiers.
