This circuit demonstrates how a resonator can be used practically , so it includes a coupling cap to feed the input signal with some source resistance , the series resistance of the inductor and loading of the measurement setup , Anyone using this should do an AC analysis from 2 to 8 MHz and see the effect of varying the coupling cap and series resistance of inductor at the output , for typical cases coupling cap with a tenth of the value of the resonator cap works best, the inductor is assumed to be air core so high frequency loss in magnetic cores is not modeled. This type of resonator can work without voltage source being part of the circuit, and therefore achieves galvanic isolation, practically the ground of the voltage source and the resonator can be very different and only limited by the breakdown voltage of coupling capacitor.
