TEXT -256 -528 Left 0 ;Crystal circuits can be best analyzed with an AC-analysis.\nIf someone resist on TRAN analysis, then he/she has to take care about time step,\nsimulation time and steady state condition.  Usually there are very long startup \ntransients which require very long simulation runs in the range up to 100ms and\nthat with a time step of 1/1000 or less of the period.\nSetting the correct initial energy in the inductor or capacitor can eleminate most of \nthe startup transient.  The correct value for the IC=xxx energy can be measured\nin the AC analysis run. Watch the IC statement of inductor L1.\n \nRun firstly the AC-analysis and load the plot settings file "crystal_ac.plt".\nThe crystal impedance(input impedance) of the circuit below is -V(v1)/I(V1) .\nThe - sign comes from the definition of V1-source current in SPICE.\n \nThe TRAN analysis use the .UIC option in the .TRAN statement. This setting\nenables an initial condition (current) of inductor L1.\nThe plot settings file for .TRAN simulation shows that the voltage leads the current\nby 90degree at a certain frequency between the series and the parallel resonance \nfrequency. A second circuit with L2 is provided to show the correct phase shift.
