Traditional quartz crystal frequency references include a large, power-starving, oven-controlled crystal oscillator (OCXO), which base stations favor because of their excellent stability. We simulated a temperature-compensated crystal oscillator (TCXO) in the stress-compensated cut (SC-cut) resonator using the C and B mode frequencies. Power-consci...

... the metal oxide silicon field effect transistor (MOSFET) was applied instead, and gate oscillation by the digital circuit was confirmed using the CMOS technology for constructing integrated circuits. Figure 5 shows a CMOS gate quartz oscillation circuit. The circuit is separated in the SC-cut for the C mode or B mode by the synchronous circuit of L 1 , L 2 , C 3 , C 4 , C 5 , and C 6 . ...
