Title: Innovations of Hui-Yi Cheng in Temperature Sensing Technology
Introduction
Hui-Yi Cheng is a notable inventor based in Hsinchu County, Taiwan. He has made significant contributions to the field of temperature sensing technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
One of his latest patents is a temperature sensing device that includes a bandgap voltage generator, N mirror current sources, a temperature voltage generator, and a temperature calculating unit. This device mirrors N mirror currents according to a positive temperature coefficient current. The temperature voltage generator sets the conducting number M of the mirror current sources based on a control signal, generating a temperature voltage. The temperature calculating unit counts the control signal and compares the potential of the temperature voltage with a reference voltage generated by the bandgap voltage generator, allowing for accurate temperature information calculation. This design reduces the circuit area and noise by controlling the conducting number M of the mirror current sources instead of using serially-connected resistors.
Another significant patent is a temperature detecting device that comprises a current source, multiple resistors, a binary counter, a multiplexer, a comparator, and control logic. The current source provides a PTAT current, while the resistors generate m voltage signals with ascending or descending voltages. The binary counter produces a binary select signal with (n+1) bits, and the multiplexer selectively outputs the m voltage signals based on this binary select signal. The comparator compares the multiplexer output signal with a reference voltage, generating a comparing signal that the control logic uses to issue a start signal. This innovative approach ensures that the reference voltage remains stable regardless of temperature variations.
