The first floating CMOS bandgap voltage reference is presented. The circuit is very suitable for precision applications in fully differential analog circuits.lt generates a continuous time low impedance voltage of 2.48V ± 24 mV before trimming. The experimental prototype occupies 1800 mils square and dissipates 6 mW with a single supply voltage of 5V. Temperature stability is better than 20 ppm/C over a temperature range from 0 to 100 degree. The measured high frequency power supply rejection of-50 dB at lOOKHz is the best ever reported.

Abstract
The first floating CMOS bandgap voltage reference is presented. The circuit is very suitable for precision applications in fully differential analog circuits.lt generates a continuous time low impedance voltage of 2.48V ± 24 mV before trimming. The experimental prototype occupies 1800 mils square and dissipates 6 mW with a single supply voltage of 5V. Temperature stability is better than 20 ppm/C over a temperature range from 0 to 100 degree. The measured high frequency power supply rejection of-50 dB at lOOKHz is the best ever reported.File in questo prodotto:
