The 2 oscillator circuits below are ideal for making use of crystal oscillators in collection or parallel method: Modeling of nonlinear micromechanical resonators and their simulation with the harmonic‐equilibrium strategy PDF The sort of amplifier you will need will depend upon the frequency. Op-amps may go at small-frequency gates minimal https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
