Abstract
A fully integrated 52 MHz frequency reference, de-
signed in a 0.35 µm CMOS process, achieves 1.7 ppm frequency
temperature accuracy within 0 to 80°C using a nonlinear com-
pensation technique. The proposed low TC
reference oscillator
achieves the lowest reported unc ompensated temperature coef fi-
cient, i.e., 65.25 ppm/°C, among the integrated frequency r efer-
ences. The output reference freq uency is obtained by dividing the
differential LC Colpitts oscillator output operating at 1.6 GHz. Os-
