Abstract: An input stage for a video receiver includes a variable gain amplifier, an analog-to-digital converter for sampling a video signal and a digital processing unit for processing digital samples of the video signal. An analog regulating circuit sets an input potential at an input of the variable gain amplifier. A differential architecture is used for the variable gain amplifier and the digital analog converter. A conversion circuit between an input coupling capacitor and the variable gain amplifier allows generating the video signal on two channels in antiphase, which are centered on the common mode voltage. Such differential architecture allows reducing the amplitude of analog signals, which is particularly advantageous in the case of a low voltage supply delivering a few volts. In addition, linearity of the video signal processing is enhanced.

Abstract: The common-mode voltage of a switched-capacitor system is controlled by determining a current common-mode voltage of the switched-capacitor system, converting (in a flow-through conduction cell) the difference between the current common-mode voltage and a desired common-mode voltage into a resultant current, and reinjecting this resultant current into the switched-capacitor system via a resistive path.
