DESIGN AND ANALYSIS OF BAND GAP REFERENCE CIRCUITS

Abstract

In this dissertation titled “Design and Analysis of Band Gap Reference Circuits”, we discuss the importance of Band Gap Reference circuits and their design. We start our discussion with two important building blocks of any band gap reference circuit i.e. circuits exhibiting the CTAT (Complementary to absolute temperature) and PTAT (Proportional to absolute temperature) nature. We later combine the above CTAT and PTAT designs to obtain a constant reference voltage which is fairly independent of temperature and supply variations over a certain pre-defined range and can be practically used in analog IC design of various electronic components. Further in our dissertation we discuss certain improvements in design of our band gap reference circuits and conclude with future scope and promises the band gap reference circuits withheld in the field of electronic design. Throughout our dissertation we analysed and simulated all the circuits using the Cadence Design Systems Software.
