    Abstract: The invention relates to a circuit for processing an analog signal presenting a time sequence of discrete signal levels. Each discrete signal level is situated in a time interval and represents an information-bearing segment of said interval while the remainder of the time interval is a non-information-bearing segment. The circuit comprises a transistor (10) configured as an emitter-follower or source-follower circuit, a high emitter or source resistance or, in place of same, a high-resistance constant current source (20) and a device (14) for applying a supply voltage, as well as a switch (24) which is connected between the emitter and a reference potential (26) and serves to prevent a current from flowing via the resistance or high-resistance voltage source (20) in case of a charge reversal of an output capacity (22) of the circuit in one direction, whereas in case of a charge reversal in the other direction the dynamic current boosting effect of the transistor (10) is utilized. This results in a rapid emitter-follower or source-follower circuit which can be used notably as output stage for image sensors.

    Abstract: A line receiver (100) comprising a switched capacitor circuit (102) and a buffer (108) is described. The buffer (108) may be configured to receive, through the switched capacitor circuit (102), an analog signal. In response, the buffer (102) may provide an output signal to a load (110), such as an analog-to-digital converter. The switched capacitor circuit (102) may be controlled by a control circuitry (112), and may charge at least one capacitive element (106) to a desired reference voltage. The reference voltage may be selected so as to bias the buffer (108) with a desired DC current, and consequently, to provide a desired degree of linearity. The line receiver (100) may further comprise a bias circuit (300) configured to generate the reference voltage needed to bias the buffer (108) with the desired DC current.
