Abstract :
It is considered the problem of synthesis of structural and schematics of bipolar analog ICs based on the classic “folded” cascode which have a small zero-level (offset voltage, Vov) and its drift in the terms of temperature and radiation effects. Thus the basis of the modernization of the scheme are adopted by well-known basic analog IC (operational amplifiers, continuous stabilizers, voltage comparators, etc.), in which by the rules set forth below, we introduce some structural redundancy, which provides a decrease Vov and its voltage drift effect on one or two orders).
