Latest Patents

One of Yu-Cheng Lin's latest patents is titled "Operating phase number dependent compensation of a multi-phase buck converter." This invention features a digital compensator that selects compensation coefficients based on the operating phase number of the multi-phase buck converter. It includes different compensators for each operation phase number, enhancing loop gain bandwidth, transient response, and stability. The multi-phase buck converter is designed to operate with more phase circuits under higher loading conditions and fewer phase circuits under lower loading conditions. This adaptive compensation optimizes the control-to-output voltage transfer function.

Another significant patent is "DC gain improvement of a digitally controlled DC-DC converter by LSB tuning." This invention proposes an easy LSB tuning method for digitally controlled DC-DC converters. It aims to increase the DC gain while minimizing steady-state error under no-limit-cycle conditions and a finite bit number. The tuning of the least significant bit (LSB) of one or more coefficients in the denominator of the discrete-time domain transfer function mitigates the round-off effect on the digital compensator's coefficients.
