Title: Ramesh Harjani: Innovator in Low Dropout Regulators and Stochastic Computation
Introduction
Ramesh Harjani is a prominent inventor based in Minneapolis, MN (US), known for his significant contributions to the field of electronics. With a total of 17 patents, he has made remarkable advancements in low dropout regulators and stochastic computation techniques. His work has had a profound impact on the efficiency and performance of electronic devices.
Latest Patents
One of Harjani's latest patents is for a low dropout regulator with smart offset. This innovative LDO regulator includes a pass transistor, a charge pump connected to the pass transistor, and an error amplifier. The error amplifier receives a voltage from the pass transistor and generates a voltage based on that input. The charge pump then generates a voltage that is lower than the original voltage by an offset, supplying it as a gate voltage to the pass transistor.
Another notable patent involves stochastic computation using pulse-width modulated signals. This invention describes devices and techniques that perform stochastic computation on analog periodic pulse signals rather than random digital bit streams. By exploiting pulse width modulation, time-encoded signals are generated by adjusting the frequency and duty cycles of PWM signals. This approach significantly reduces latency, area, and energy consumption compared to prior stochastic methods. Circuits synthesized with this technique can operate as efficiently as conventional binary designs while maintaining the advantages of fault tolerance and low cost.
