The passive resistors of quadrature-phase shifter can be shared by the startup circuit to save area consumption. The double-edge extractor and the low-power comparator are added to reduce the power consumption. The proposed 32.768-kHz energy-efficient SCXO, fabricated in a 40-nm CMOS technology, consumes 34.3 nW under a 1 V supply. © 2017 IEEE. |
