Switched-capacitor buffer and related methods

A line receiver comprising a switched capacitor circuit and a buffer is described. The buffer may be configured to receive, through the switched capacitor circuit, an analog signal. In response, the buffer may provide an output signal to a load, such as an analog-to-digital converter. The switched c...

Zusammenfassung:	A line receiver comprising a switched capacitor circuit and a buffer is described. The buffer may be configured to receive, through the switched capacitor circuit, an analog signal. In response, the buffer may provide an output signal to a load, such as an analog-to-digital converter. The switched capacitor circuit may be controlled by a control circuitry, and may charge at least one capacitive element to a desired reference voltage. The reference voltage may be selected so as to bias the buffer with a desired DC current, and consequently, to provide a desired degree if linearity. The line receiver may further comprise a bias circuit configured to generate the reference voltage needed to bias the buffer with the desired DC current.
