| 主权项 | 1. Apparatus for electrically connecting measurement apparatus to a biological subject, the apparatus including a signal delivery circuit including: a current buffer having: a current buffer input for receiving a signal from a signal source; and,a current buffer output for supplying a current to an electrode attached to the biological subject; a voltage buffer having: a voltage buffer input coupled to the current buffer output; and,a voltage buffer output for providing a voltage signal indicative of a voltage at the electrode, to a sensor; and a DC offset control circuit coupled between the voltage buffer output and the current buffer input. | ||
