Latest Patents

One of his latest patents is for a digital condenser microphone that features a preamplifier with variable input impedance. This invention includes a method for controlling the variable input impedance of the preamplifier. The preamplifier is designed with a bias terminal that applies a bias voltage to the input signal from the microphone condenser. Additionally, an impedance unit with at least one variable input impedance element is connected to the bias terminal. An operational amplifier processes the input signal and converts it into an output signal. A control block monitors the DC voltage level of the output signal and adjusts the total impedance of the impedance unit accordingly.

Another notable patent addresses a circuit and method for reducing pop-up noise in a digital amplifier. This circuit includes a switch unit and a switch signal generator. The switch unit is connected in parallel to an output load and controls the current flowing through the load by creating a conduction path in response to a switch signal. The switch signal generator produces the switch signal based on a power-on or power-off control signal, effectively minimizing pop-up noise during the amplifier's operation.
