Hi guys,
I'm trying to simulate 1.05 GHz LFE AIN MEMS resonator with LTSPICE. When I simulate the circuit without the resonator, it was able to achieve about 32dB. But after I connect the resonator to the circuit, the node for Vout and Vin were missing. I changed the resonator to 10MHz and it works fine with this circuit. This is my circuit. Does anyone know how to fix this?
