I followed the video at the link http://www.analogzoo.com/2015/07/ . The video directs watchers to a tool at http://www.analogzoo.com/lab/pierce_bjt.html to help determine parameters to cause resonation/clock generation.
I watched the video a few times and added appropriate parameters in the tool to get a Crystal Load Capacitance, Crystal Loaded Q, and Gain Margin in spec with what the video describes.
I match my Crystal Load Capacitance to my crystal of 12pf. I have a Q of about 87 and a Gain of about 5. If I built the circuit, I would think it would resonate.
Everything looks good, yet, my Crystal Drive Level is at 0uw.
Does this matter? I understand this to be the power consumed by the crystal and that too much can damage the crystal. Having 0 is probably a good thing. I am wondering about that. I have 5 Volts supplied. 2.5 peak to peak, c1 and c2 = 182pf, etc,
If I built this circuit, what lines show resonation? I am expecting to put my oscilloscope to ground and the line (on the right side) between the amplifier and the crystal. I would expect it to oscillate about 6.4 Mhz.
If I do this, I then would wish to put some counters to divide the clock a few times and see the division on my scope. Should adding additional ICs to divide the clock couse the clock to change much?
