Title: The Innovations of PakriSwami Elango
Introduction
PakriSwami Elango is a notable inventor based in Singapore, known for his contributions to the field of electronics. He holds 2 patents that showcase his innovative approach to technology. His work primarily focuses on amplifiers and current sensing devices, which are crucial in various electronic applications.
Latest Patents
One of his latest patents is the "Power amplifier with bootstrap voltage clamp." This invention features an amplifier output stage that includes an output transistor connected to a high supply voltage. The design incorporates a bootstrap terminal linked to a control terminal of the output transistor through control circuitry. A capacitor is arranged between the bootstrap terminal and the output terminal to elevate the voltage at the bootstrap terminal above the high supply voltage. Additionally, circuitry is included to limit the voltage at the bootstrap terminal to a predetermined threshold, directly affecting the control terminal of the output transistor to reduce its conductivity when necessary.
Another significant patent is the "Bidirectional load current sense circuit for a H-bridge." This invention relates to a current sense device for a load arranged in a diagonal of an H-bridge comprising MOS transistors. It features a sensor independent from the H-bridge for measuring the current flowing in the load. A current-voltage converter transforms the measured current into a voltage proportional to that current, which is then applied to a sense amplifier that determines the transconductance gain of a control amplifier for the transistors of the H-bridge.
