Latest Patents
One of her latest patents is a high-speed voltage regulator with integrated lossless current sensing. This invention describes a high-speed multi-phase voltage regulator capable of sensing load current. For each phase leg, the voltage regulator includes a current mirror to mirror current in switching elements, a current sense to detect high-side current in the current mirror, and an I-V converter to convert the sensed high-side current to a voltage. The high-side sensed current for each phase leg is averaged, and the duty cycle for the voltage regulator is extracted. The average high-side sensed current and the duty cycle are converted to digital by an A-D converter. Digital circuitry corrects the sensed current by adjusting for the gain and offset voltage of the voltage regulator. The adjusted sensed value is divided by the duty cycle to convert to load current, and the average load current is multiplied by the number of phases operating to determine overall load current.
Another notable patent involves developing a desired output sampling rate for oversampled converters. This invention allows an analog-to-digital converter to achieve an output sampling rate that is not an integer multiple of the system clock. This is accomplished without using the conventional phase-locked loop circuit, which generally requires a longer design time, more testing, and more silicon area. Instead, a pseudo clock is generated from the system clock by disabling some of the system clock pulses to achieve a pseudo clock with the desired effective frequency.
