He has made significant contributions to the field of electronics, particularly in the development of advanced circuits and systems. With a total of 2 patents to his name, Wallace's work has had a meaningful impact on technology.
Latest Patents
Wallace's latest patents include the "Dual Adjust Current Controlled Phase Locked Loop" and the "Power Reduction Technique for Current Mode Digital-to-Analog Converters." The dual adjust current-controlled phase locked loop allows for multiple-gain frequency acquisition of a signal. It features a phase detector that responds to both a reference signal and a synthesized signal, producing a phase error signal. The controller generates coarse and fine adjust control signals, which are used by a dual adjust current-controlled oscillator to modify the oscillating frequency of the synthesized signal. This oscillator includes a differential current-controlled ring oscillator with a series of delay elements, each equipped with high and low gain circuits for precise adjustments.
The second patent, the power reduction technique for current mode digital-to-analog converters, presents a video DAC designed to drive video displays with reduced power dissipation. This is achieved through a dual driver circuit connected to a current mirror, which consists of a strong driver and a weak driver. The dual driver allows for the switching of current between the video load and a dummy load, effectively reducing power consumption during steady video signals and synchronization periods.
