Title: Siyaram Sahu: Inventor in Clock and Oscillator Technologies

Introduction

Siyaram Sahu is an inventor based in Bari Raisen, India. His work includes innovations in crystal oscillator leakage-current compensation and clock generation with duty-cycle correction. He is associated with NXP, and his portfolio includes 8 patents.

Latest Patents

One of Sahu’s latest patents, “System and Method of Compensating Crystal Oscillator Pad Leakage Current,” describes a system designed to reduce leakage current in a crystal oscillator. It uses a DC level comparator, current compensation circuitry, and a compensation controller. The comparator evaluates voltage levels at two nodes and provides a signal that guides the controller. The circuitry then sources or sinks current at a node to minimize leakage. A digital counter may help select the current sources or sinks used for compensation.

Another patent, “Quadrature Phase Shifted Clock Generation with Duty Cycle Correction,” describes a method for generating quadrature phase-shifted clocks while correcting duty cycle. A delay circuit produces a delayed clock from a reference clock, with the delay determined by a control value. The method adjusts two edge values based on the states of the reference and delayed clocks, then uses those values to update the control value.
