Abstract: A single-trim, highly accurate Colpitts-based frequency reference is presented. Our analysis shows that the Colpitts-topology outperforms the cross-coupled LC-topology in terms of temperature stability. Measurements on prototypes in a 0.13- $\mu \text{m}$ high-voltage CMOS silicon… read more here.
