Abstract
A two-channel programmable signal-conditioning chip for implantable purposes is discussed. The signal-conditioning chip has been optimized to operate with low power, low noise, and high accuracy. Each channel consists of an instrumentation amplifier (IA) and two switched-capacitor filters. the gain of the IA and the cutoff frequency of the filter can be set under software control
