Lamb-Wave Resonator Oscillator Powered by Inductive Compensation of Stray-Capacitance CMOS Inverter

抄録

In this study, we studied Lamb wave resonator driver circuit with inductive compensation of the internal capacitance to improve the frequency limit by the transition frequency f_T which is one of the important parameters of active components for deciding amplification and oscillation. Comparing with an SAW resonator, the Lamb-wave oscillator can provide highly stable frequency-temperature characteristics and smaller frequency deviation at the normal temperature. The inductive cancellation scheme of the internal capacitor of the CMOS inverter realizes oscillation over f_T.
