Title: Innovations by Sunil Rajan

Introduction

Sunil Rajan is a prominent inventor based in Bengaluru, India. He has made significant contributions to the field of technology, particularly in the area of phase interpolation and built-in self-test operations. With a total of four patents to his name, Rajan continues to push the boundaries of innovation.

Latest Patents

Sunil Rajan's latest patents include methods for determining and calibrating non-linearity in a phase interpolator and related devices and systems. These methods and systems are designed to determine a first jitter value that causes the bit error rate (BER) of a data sequence to exceed a predefined target BER. This occurs when a recovered clock is aligned with the data sequence at a first PI code. The recovered clock is obtained from a data pattern representing the data sequence. Additionally, the patents detail how to determine a second jitter value that causes the BER to exceed the predefined target at a second PI code. The first PI code may immediately precede or succeed the second PI code. Furthermore, the embodiments determine a Differential Non-Linearity (DNL) corresponding to the second PI code, based on a phase shift introduced to the recovered clock by the second PI code relative to the first PI code, along with the first and second jitter values. All DNL values corresponding to all PI codes may be determined in a similar manner. An Integral Non-Linearity (INL) may also be determined by integrating the DNL corresponding to all PI codes. Another significant patent involves methods and systems for performing built-in self-test operations without a dedicated clock source. In this system, receiver lanes of a multilane receiver are configured to perform BIST operations, with at least one lane acting as a synthesized clock source for the others.
