Description
This webinar provides detail about General Purpose Bandgap Reference. The basic working principle of Bandgap reference circuits is explained . The circuit implementation is discussed and the issues with each implementation style is mentioned. Index Terms—Bandgap Reference, CTAT, PTAT, Current mirror, OpAmp.A Bandgap Reference is a circuit which gives a constant voltage output Vref irrespective of temperature, process and supply voltage variations. It is an especially important component of several analog and mixed signal Integrated Circuits. Several circuits such as LDO, ADC, DAC, Buck convertor. use Bandgap reference as a building block. It provides a constant output reference voltage of 1.2V which is proportional to the Bandgap energy of Silicon(1.2eV)at 0K and hence, gets its name as Bandgap Reference circuitFor detailed information regarding the Bandgap Reference circuit, refer to VLSI System Design website.
