title: Dual-path capacitance compensation network for microelectrode recordings.
abstract: Commercially available microelectrode preamplifiers have a built-in capacity compensation circuit. When a shielded cable is utilized to transmit the signal from the microelectrode to the preamplifier the compensative ability of this circuit may be inadequate and may result in a less than desired frequency response. We describe a dual-path capacitance compensation circuit that resolves this problem without impairment of the shielding properties.
