Latest Patents

One of Fortier's latest patents is titled "Multiplying delay locked loops with compensation for realignment error." This invention provides a control circuit, a multiplexed oscillator, and an integrate and subtract circuit. The control circuit selectively injects a reference clock signal into the multiplexed oscillator, which operates with an injected period when the reference clock signal is present and with a natural period when it is not. The integrate and subtract circuit tunes the oscillation frequency of the multiplexed oscillator based on the difference between the integration of the oscillator signal over the injected period and the natural period.

Another notable patent is the "Low-power class D amplifier using multistate analog feedback loops." This audio amplifier system features analog class-D amplifiers and utilizes Natural Sampling Pulse Width Modulation (PWM) to convert an analog input into a series of Rail-to-Rail pulses. The audio signal is encoded in the average value of the PWM pulse train and can be recovered through analog low pass filtering. The Class-D amplifiers are designed with a negative feedback loop to suppress non-idealities introduced by the Class-D switching stage, ensuring high-quality audio output.
