Title: Innovations by Herman Cheung
Introduction
Herman Cheung is a notable inventor based in Cupertino, California. He has made significant contributions to the field of programmable logic devices, holding a total of eight patents. His work focuses on enhancing power applications through innovative memory and control systems.
Latest Patents
One of his latest patents is titled "Compensation memory (CM) for power application." This invention involves a memory block integrated into a programmable logic device (PLD). The memory block includes one or more lookup tables that store pre-populated data. The PLD features a programmable fabric and a signal wrapper that facilitates communication between the memory block and the programmable fabric. The memory block is designed to receive input signals from the signal wrapper and generate output signals by referencing the pre-populated data. Additionally, the pre-populated data can be programmably altered by adjusting parameters of the programmable fabric and loading new data into the lookup tables via the signal wrapper.
Another significant patent is the "Pulse-width modulation (PWM) control loop for power application." This method involves receiving error signals from a signal wrapper of a programmable fabric integrated within a PLD. The process includes looking up pre-calculated data in one or more lookup tables to find a match corresponding to the error signals. A compensated output signal is then generated using this matching data to drive a switch in the power regulator. Similar to his previous patent, the pre-populated data in the lookup tables can be modified by programming parameters of the programmable fabric.
