Latest Patents

One of his latest patents is titled "Feedback controller having multiple feedback paths." This invention involves a feedback controller that comprises first and second feedback circuits. The first feedback circuit connects an input node to an output node and includes an error node. It features a feedback amplifier that compares a feedback signal to a reference signal, providing an error signal, and a comparator that compares the error signal to a second reference signal, yielding an output signal. The second feedback circuit connects the input node to the error node and includes a current source coupled to the error node, along with a controller that manages the current source based on the feedback signal's value relative to a threshold.

Another notable patent is the "Gain control circuit." This circuit includes a resistor with two terminals and an operational amplifier. The inverting terminal of the operational amplifier is electrically coupled to the first terminal of the resistor. The circuit transforms voltage changes at the operational amplifier's output into a substantially exponential current change. This gain control circuit is designed to perform wide bandwidth input signal buffering with linearity under low voltage and low power conditions, while also minimizing circuit size and manufacturing costs.
