The design, implementation, and characterization of UHF and L-band generalized Pierce oscillators using two-pole thin-film resonator (TFR)-based filter configurations and silicon delay lines in the feedback circuit as a precursor study to direct integration are reported. Circuit analysis and the design procedure use discrete-element models implemented with SPICE 2G. Onset of oscillation was computed using the Barkhaussen criteria and measured data for both commercial amplifier modules and the TFR filters and delay lines. Experimental measurements show phase noise performance from -90 dBc/Hz to -100 dBc/Hz at 1 kHz with carrier frequencies of 1200 MHz.
