Latest Patents
One of Larsson's latest patents is a trimming method of DCR sensing circuits. This invention provides an improved method for trimming a DCR sensing circuit, which is sensitive to self-heating or has a large tolerance. The circuit includes a resistive divider circuit coupled to a sensing element, featuring a trim resistor and two test points. Before trimming the trim resistor, the actual resistance of the sensing element is determined. A target voltage across the trim resistor is calculated based on the determined sensing element resistance and a known small trim current. This small trim current is injected during the trimming process to avoid self-heating of the sensing element. The trim resistor is then adjusted while monitoring the voltage across it.
Another significant patent by Larsson involves a switched mode power supply compensation loop. This controller includes a sampling module that samples a signal indicative of the output voltage. It also features a filter module that filters out a ripple component of the sampled signal to generate a filtered signal. A proportional-integral-derivative (PID) controller generates a duty cycle control signal, incorporating various components that work together to optimize the performance of the power supply.
