【简　介】:Ab.~tract—A precision curvature-compensated switched-capacitor bandgap reference is described which employs a standard digital CMOS process and achieves temperature stability significantly lower than has previously been reported for CMOS circuits. The theoretically achievable temperature coefficient approaches 10 ppm/ 0 C over the commercial temperature range utilizing a straightforward room temperature trim procedure. Experimental data from monolithic prototype samples are presented which are consistent with theoretical predictions. The experimental prototype circuit occupies 3500 milsz and dissipates 12 mWwith+5Vpowersupplies,The proposedreferenceis helieved to be suited for use in monolithic data acquisition systems with resolutions of 10 to 12 bits.
