The 2 oscillator circuits underneath are suited to employing crystal oscillators in sequence or parallel mode: Modeling of nonlinear micromechanical resonators as well as their simulation Along with the harmonic‐harmony technique PDF The kind of amplifier you may need will depend upon the frequency. Op-amps may match at reduced-frequency gates https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
