Abstract

Bandgap Reference (BGR) circuit is to yield a precise and accurate dc voltage which has minimum variation over an external influence. The objective of this BGR paperwork lies on using two different temperature-compensation techniques which are based on the resistor-subdivision method and resistor-less method on same BGR circuit structure. This project has been successful simulated in CMOS 0.18-μm technology and provides the optimized corner analysis results; which includes output reference voltage at 910.88 mV with maximum temperature-coefficient (TC) of 12.99 ppm/°C. Maximum power consumption at 1.8V supply voltage is reported at 2mW.
