CL1 and CL2 are two single-ended load capacitors used to control initial frequency accuracy of the crystal. One concept to help in the design of crystal oscillators is "negative resistance", or –R. Negative resistance is WebThe crystal is operated near series resonance, so it looks like a resistor, and that resistor forms a second lag network for almost another 90 degree phase shift. The inverting amplifier supplies 180 degree phase shift plus a little more because it is not infinite bandwidth. See, for example, Matthys pages 45–53. citi furniture expandable dining tables
