웹2.1 Bandgap Reference Core A stable BGR voltage with temperature is obtained by Voltage Complementary to Absolute Temperature (VCTAT) derived from the BJT base-emitter voltage (VBE) compensated by the Voltage Proportional to Absolute Temperature (VPTAT) by the difference of VBE voltages of n number BJT operated under different current densities. A bandgap voltage reference is a temperature independent voltage reference circuit widely used in integrated circuits. It produces a fixed (constant) voltage regardless of power supply variations, temperature changes, or circuit loading from a device. It commonly has an output voltage around 1.25 V (close to the theoretical 1.22 eV (0.195 aJ) band gap of silicon at 0 K). This circuit concept was first published by David Hilbiber in 1964. Bob Widlar, Paul Brokaw and others followed up with ot…
