Latest Patents

Xi Chu holds a patent for a "Two-stage non-linear filter for analog signal gain control in an OFDM receiver." This invention features an analog signal gain control circuit (ASGC) that includes a digital variable gain amplifier (DVGA). The DVGA is designed to control the gain of a received signal, ensuring it achieves a desired amplitude that matches the dynamic range of an analog-to-digital converter (ADC). The invention also incorporates an inverse scaling stage and a two-stage fast attack and slow decay filter. This filter rapidly responds to increases in signal amplitude while slowly decaying the control signal in response to decreases in input signal amplitude.
