WebTherefore, the band gap needs to be chosen based on a compromise between efficient absorption of broadband sunlight and a high voltage output. The bandgap energy of silicon (1.12 eV), the so far highly … 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…
