چکیده
This paper describes the design of a bandgap reference, implemented in 0.50 μm CMOS technology. The circuit generates a reference voltage of 1.2218V. It can operate between 20oC & 70o C. Total variation of reference voltage within the temperature range is 2.6mV which is 0.213% of the reference voltage. This circuit works in a current feedback mode, and it generates its own reference current, resulting in a stable operation. A start-up circuit is required for successful operation of the system. Keywords— Analog Integrated Circuit, Bandgap Reference, CMOS, Temperature Independence.
