Abstract
Possibilities and limitations are considered of realizing integrated analog filters with cut off frequencies below 10 Hz. To arrive at an acceptable low chip-area, electronic multiplication is required to enhance the time-constant(s). It is recognized that for a given supply voltage electronic multiplication reduces the dynamic range because of noise-and DC-offset multiplication. As an example a 10 Hz low-pass filter has been successfully integrated on 0.4 sq. mm of chip area in a BICMOS process.
