Title: Innovations by Seetharaman Janakiraman

Introduction

Seetharaman Janakiraman is a prominent inventor based in Bengaluru, India. He has made significant contributions to the field of analog-to-digital converters, particularly in the design and efficiency of successive approximation register (SAR) ADCs. With a total of five patents to his name, Janakiraman continues to push the boundaries of innovation in his field.

Latest Patents

One of his latest patents focuses on reducing the effect of elements mismatch in a SAR ADC. This invention involves converting an intermediate set of bits into first and second intermediate analog values from two sets of representative capacitors. By selecting capacitors that are not the same, the output code of the SAR ADC is generated, enhancing the resolution of an N-bit SAR ADC through the generation of multiple N-bit digital codes. Each transfer function is offset by a fraction of the least significant bit (LSB) value, allowing for the addition of these codes to form a P-bit digital code, where P is greater than N.

Another notable patent is for a low power comparator designed for use in SAR ADCs. Traditional comparators consume significant power, making it essential to develop a more efficient configuration. Janakiraman's invention introduces a multi-bandwidth comparator that can switch between different coarse and fine resolutions. This innovation achieves lower power consumption while occupying a minimal area, thus enhancing the overall efficiency of SAR ADCs.
