EE 214 Lecture 27 (HO#35) B. Murmann 1 Lecture 27 Bandgap Reference (Continued) Boris Murmann Stanford University [email protected] Copyright © 2004 by Boris Murmann EE 214 Lecture 27 (HO#35) B. Murmann 2 Overview Reading 4.4.3 (Temperature Insensitive Biasing) Introduction Today's lecture will cover several important details that we've left out in our previous analysis of bandgap references. We will discuss nonidealities such as "curvature" and the impact of offset voltages. Finally, we will take a brief look at state-of-the art implementations and performance.
