Title: The Innovations of Tan Kee Hian

Introduction

Tan Kee Hian is a prominent inventor based in Singapore, known for his contributions to the field of digital electronics. He holds a total of 4 patents, showcasing his innovative approach to technology and engineering.

Latest Patents

One of his latest patents is a digital-to-analog converter (DAC)-based voltage-mode transmit driver architecture with tunable impedance control and transition glitch reduction techniques. This invention includes a transmit driver circuit that features an impedance control circuit coupled to multiple DAC driver slices. The impedance control circuit is designed to be adjustable, allowing it to match the load impedance for the transmit driver circuit. Another notable aspect of this invention is that the output impedance is smaller than the load impedance, enabling a greater output voltage swing at the differential output nodes than the voltage of the power supply rail. Additionally, the circuit incorporates a predriver circuit with inverters that have transistors of varying strengths.

Another significant patent involves calibrating a multiplexer of an integrated circuit. This multiplexer calibration system consists of main MUX circuitry, first replica MUX circuitry, digital-to-analog (DAC) circuitry, detection circuitry, and control circuitry. The main MUX circuitry processes clock signals to output a first data signal, while the first replica MUX circuitry also processes the clock signals to output a second data signal. The DAC circuitry generates an offset voltage, and the detection circuitry produces a first error signal based on the second data signal and the offset voltage. The control circuitry then generates a control signal to adjust the clock signals accordingly.
