US Patent Issued to GIGADEVICE SEMICONDUCTOR on March 24 for "Channel selection circuit, analog-to-digital converter and system-on-chip" (Chinese Inventor)

ALEXANDRIA, Va., March 24 -- United States Patent no. 12,587,204, issued on March 24, was assigned to GIGADEVICE SEMICONDUCTOR INC. (Haidian, China).

"Channel selection circuit, analog-to-digital converter and system-on-chip" was invented by Lipeng Wu (Haidian, China).

According to the abstract* released by the U.S. Patent & Trademark Office: "A channel selection circuit, an analog-to-digital converter (ADC) and a system-on-chip (SoC) are provided. During a sampling phase of an ADC circuit, a substrate voltage of a MOS switch in a selected channel is set to a voltage of analog input signal to which the channel is coupled. This eliminates the body-bias effect of the MOS switch, greatly improving linearity of the channel selection circuit a...
