Filtering circuits, the most ubiquitous of electronic signal-processing functions, made for spirited discussions as analog-to-digital technology solutions unfolded. Bedrich Hosticka's 1978 paper on a MOS switched-capacitor filter marked the beginning of the dominance of switched-capacitor techniques for integrated audio-band filtering. In the ISSCC 40th Anniversary Commemorative Supplement in 1993, Robert W. Brodersen remembered that in the year following Hosticka's paper two papers at ISSCC 1979 demonstrated the manufacturability of the approach in high-volume applications. The circuit served as part of an icon of the era of IC telecom, when a chip plot of 30 poles of switched-capacitor filtering by B.J. White, G. M. Jacobs, and G.F. Landsburg hung in the New York Museum of Modern Art for a number of years.
