摘要: A micropower signal-processor IC is the key component of an implantable telemetry system for neurophysiology. The bipolar/JFET/I/SUP 2/L chip uses digital and low-noise analog circuitry to amplify, filter, multiplex eight channels neutral, electrogram, temperature data from unanesthetized freely moving animals. Fully integrated continuous-time bandpass amplifiers incorporate a frequency-sensitive feedback network prevent amplification input offset voltage. can telemeter over 500 h, permitting long-term neurophysiological investigations.
