Title: Innovator Spotlight: Suvankar Biswas

Introduction

Suvankar Biswas is a notable inventor based in Blacksburg, Virginia, recognized for his contributions to advanced electronic circuit design. His innovative approach has led to the development of two significant patents, enhancing efficiency in electrical applications.

Latest Patents

1. **Low Voltage Drop Cascaded Synchronous Bootstrap Supply Circuit**

This patent describes a cascaded synchronous bootstrap supply circuit that reduces the voltage drop between bootstrap capacitors. By replacing traditional bootstrap diodes with gallium nitride (GaN) transistors, Suvankar has achieved a much lower forward voltage drop. This innovation is crucial, especially as the number of circuit levels increases.

2. **Enhancement Mode FET Gate Driver IC**

Suvankar’s second patent presents a fully integrated GaN driver. This device combines a digital logic signal inverter, level shifter circuit, under-voltage lockout (UVLO) circuit, output buffer stage, and optionally, the FET to be driven—all in a single package. The level shifter circuit transforms a ground reference 0-5 V digital signal into a 0-10 V output, enabling efficient control of high side and low side GaN FETs through digital voltage.
