Latest Patents

Among his latest patents is the "Unified retention and wake-up clamp apparatus and method." This invention describes a controller that provides in-situ state retention using a closed loop global retention clamp. The controller effectively addresses di/dt and reliability constraints through an adaptive scheme, allowing for quick changes in steps with smaller current while managing larger current changes more slowly. Additionally, the loop controller of a voltage regulator is modified to control not only retention Vmin during low power states but also to facilitate fast wake-up from these states.

Another significant patent is the "All-digital closed loop voltage generator." This apparatus includes a plurality of devices connected to both an input and output power supply rail. The first circuitry is designed to turn on or off one or more devices based on a control signal. The second circuitry features an all-digital proportional-derivative mechanism that generates the control signal according to a digital representation of the voltage on the output power supply rail.
