Title: Abhirup Lahiri: Innovator in Voltage Reference and Oscillator Technologies

Introduction

Abhirup Lahiri is a prominent inventor based in Delhi, India. He has made significant contributions to the field of electronics, particularly in the development of voltage reference generators and oscillators. With a total of 16 patents to his name, Lahiri's work showcases his innovative approach to solving complex engineering challenges.

Latest Patents

One of his latest patents is the Feedback Stabilized Ring Oscillator. This invention features a ring oscillator that comprises an odd number of inverters. The output of an inverter drives a capacitor, which feeds into the next inverter. A feedback element generates two currents with a fixed ratio, applying the same voltage over the ring oscillator as over a parallel resistor connected to a current compensator. This design ensures that the current through the compensator and a parasitic current component are balanced according to the defined ratios.

Another notable patent is the Fractional Bandgap Reference Voltage Generator. This circuit generates a complementary to absolute temperature (CTAT) voltage and a proportional to absolute temperature (PTAT) current. The output current circuit creates a sink PTAT current and a source PTAT current that are equal. A resistor connects the two nodes, and a divider circuit generates a divided CTAT voltage applied to the first node. The voltage at the second node serves as a fractional bandgap reference voltage, combining the divided CTAT voltage and a proportional voltage drop across the resistor.
