Title: Chia-Jung Yeh: Patent Work in Bandgap Reference Voltage Generation

Introduction

Chia-Jung Yeh is an inventor associated with Hsinchu City, Taiwan, and Novatek Microelectronics Corp. His listed patent concerns a circuit technique for generating a voltage with a zero temperature coefficient.

Latest Patents

Yeh’s listed patent is “Bandgap Reference Voltage Generation Device.” The invention includes a proportional-to-absolute-temperature (PTAT) current generator, a bandgap reference voltage generation circuit, and a current compensator. The generator produces a first PTAT current, while the circuit produces a second PTAT current with a different positive temperature coefficient. The compensator retrieves both currents, combines subtraction and addition to generate a compensation current, and sends that current to the bandgap circuit to produce a zero-temperature-coefficient voltage. Yeh is credited with 1 patent in the information provided.
