Latest Patents

One of his latest patents is titled "Charge pumping using adjustable capacitor." This invention describes a voltage supply circuit that generates a voltage on a voltage supply node. The circuit includes an adjustable capacitor, an alternating voltage source, a charge source, and an adjusting circuit. When the alternating voltage on the second capacitor terminal transitions low, the voltage on the first capacitor terminal also becomes low, allowing the charge source to provide charge to the first capacitor terminal of the adjustable capacitor. Conversely, when the alternating voltage on the second capacitor terminal transitions high, the voltage on the first capacitor terminal also becomes high, enabling charge to be pumped from the first capacitor terminal to the voltage supply node. The adjusting circuit periodically samples the voltage on the voltage supply node and adjusts the capacitance of the adjustable capacitor to optimize that voltage.

Another significant patent is "Current sensing by using aging sense transistor." This invention presents a current sense circuit that allows for accurate sensing of a power current flowing through a power transistor as it ages. The circuit comprises a power transistor, a sense transistor, and a pull-up component. The control nodes of both transistors are connected, ensuring that they operate simultaneously. When power is supplied to the pull-up component and both transistors are off, the pull-up component forces the voltage at the sense transistor input node to be approximately equal to that at the power transistor input node, allowing both transistors to age together.
