Abstract

There is an increasing interest in high-speed signal processing in modern telecommunication and consumer electronics applications. HDTV, ISDN. A limiting factor in Op-Amp based analog integrated circuits is the limited useful frequency range. This research program will develop a new CMOS Op-Amp architecture with improved gainband width product. The new design CMOS Op-Amp will achieve up to 100MHz unity gainband width with a 1.5-micron design rule.
