    摘要： Described herein is a multi-channel biopotential signal acquisition system (900) in which a plurality of biopotential channels is corrected for common-mode interference. Each biopotential channel comprises an electrode (910, 920, 930, 940) for providing a biopotential input signal and an associated amplifier (950, 960, 970, 980) for amplifying the biopotential input signal and for providing a biopotential output signal (955, 965, 975, 985) that is processed in a processor (250, 260, 270, 990). Each biopotential output signal (955, 965, 975, 985) is passed to a common-mode feedback system (810) that determines an average common-mode signal and feeds that signal back to each of the amplifiers (950, 960, 970, 980) in each of the biopotential channels to enhance common-mode rejection ratio of the system (900).

    摘要： The invention provides a biopotential signal acquisition system, comprising at least two active electrodes (10,16) each for receiving a signal from an input, for example in the form of a respective patient contact. A unity gain buffer (32) is used to feed forward a signal from an associated input and provide the buffered output to the amplifiers of the active electrodes as a reference signal. The buffered signal is approximately equal to the input common mode signal so that the effective common mode input voltage appearing at the inputs of each amplifier is significantly reduced. This reduces the common mode gain of the active electrodes and thus improves their common mode rejection ratio while also avoiding saturation of the active electrodes.
