Clapp Crystal Oscillator (Crystal#3)

Clapp (modified Colpitts) Crystal Oscillator circuit using 2N3904 NPN transistor with single 5V power C20 is 100pF instead of 270pF in CN3165. The signal amplitude is larger. In real world, this circuit works fine, but it will not start to oscillate because it is too ideal and stable and will not start in simulation. Toggle (On then Off) the [Start] button to add a stimulus to start oscillation.
