Latest Patents

Ling-miao Chou holds a patent for a Class-D amplifier that is designed to reduce power noise. This amplifier includes a loop filter circuit, comparator circuitry, output circuitry, and common-mode control circuitry. The loop filter circuit generates first and second signals based on input and output signals, adjusting common-mode levels according to a first common-mode signal. The comparator circuitry compares a ramp signal with the first and second signals to produce pulse signals, while the output circuitry generates output signals based on these pulse signals. The common-mode control circuitry performs an AC-coupling operation on the power supply voltage to create a noise signal, which is then used to generate common-mode signals.
