Temperature compensation methods for junction‐isolated analog integrated circuits and their applications

This paper proposes temperature compensation methods used to improve circuit construction and to realize integrated circuits even at temperatures exceeding 200°C. The main purpose of a temperature compensation method is to maintain stability of dc bias in the high‐temperature range. The method is applied to the operational amplifier (OP‐AMP) to increase efficiency and to facilitate application to other circuits. A new OP‐AMP which can operate at high temperature is presented.
