Latest Patents

One of Matamura's latest patents focuses on power efficiency in an analog feedback class D modulator. This innovation provides systems and methods for architectures that enhance the power efficiency of class D modulators. Specifically, it introduces a digital feed-forward loop that allows for the removal of signal content from the input to an analog-to-digital converter. This means that the ADC processes only noise and/or error, resulting in a low-power loop filter that processes error content without signal content. Another notable patent addresses power efficiency in an audio playback path. This invention offers circuit configurations that maintain audio playback performance while reducing power consumption. It adjusts the gain for a current analog-to-digital converter based on the amplitude of the input signal and provides methods for transitioning between modes of operation for large and small signals.
