Latest Patents

Among his latest innovations is a negative voltage generator. This circuit is capable of generating a negative voltage on a negative voltage supply node. The design includes a negative voltage generation circuit, an oscillator, and an oscillator control signal generator. The negative voltage generation circuit produces a negative voltage in response to signals from the oscillator. The generated negative voltage is influenced by the frequency of the oscillator's signal. The oscillator control signal generator adjusts the frequency based on the negative voltage present, ensuring that the charge is replenished to match the demand from the supply node.

Another notable patent is a system for controlling the inductor current of a boost converter. This system features a start-up controller that generates a control signal with a fixed on-time duration and a dynamic off-time duration that decreases with each cycle. The pulse width modulation (PWM) circuit generates a PWM signal that transitions states based on the inductor current. This innovative approach allows for effective control of the inductor current during the start-up phase of the boost converter.
