Analog electronics: lecture 25

Abstract

The lecture is about Band Gap References. The instructor discusses a bandgap voltage reference which is a temperature independent voltage reference circuit widely used in integrated circuits. Looks at how it produces a fixed (constant) voltage regardless of power supply variations, temperature changes and circuit loading from a device. A bandgap voltage reference commonly has an output voltage around 1.25 V (close to the theoretical 1.22 eV bandgap of silicon at 0 K)
