Could some electronics/SPICE guru please help ? I have a simple model of a quartz crystal, as used in an oscillator. With my SPICE simulation, I can measure both the parallel and series resonant frequencies of the "pure" crystal. However, when I attach the same crystal to a biasing circuit, and run the simulation, the output is a flat DC offset. The biasing circuit involves two CMOS(1.0u micron gate length) inverters, as well as the large value feedback resistor, capacitirs etc. Is there anything special I need to do ? Any hints/suggestions would be helpful. Thanks in advance.
