Latest Patents

Choi's latest patents include a "Decision feedback equalizer robust to temperature variation and process variation." This invention features a decision feedback equalizer that comprises a positive signal line, a negative signal line, a sense amplifier, a feedback driver, a load unit, a differential driver, and a charge pump. The differential driver is designed to maintain a difference between the first voltage of the positive signal line and the second voltage of the negative signal line at a last time point of the normal period, ensuring it is equal to or greater than the reference voltage. This is achieved by adjusting the strength of the positive and negative input currents based on a temperature signal. Additionally, the charge pump provides offset voltages to maintain the average voltage at a specified value.

Another significant patent is the "Method for driving SERDES circuit." This method aims to optimize the space utilization of the SERDES circuit. It involves generating a common clock signal from a phase locked loop (PLL) and distributing this signal to both an eye opening monitor and a data transmission lane within the SERDES circuit. This innovative approach enhances the efficiency of the circuit's operation.
