Dear all:
I built the Colpitts oscillator given in the diagram below. The transistor model is 2N2222A, all
bypass capacitors are WIMA MKS4 (metalized Polyester), 100 nF. Capacitors of the tank circuit are ceramic.
When measuring the output under no load with the oscilloscope, the resulting sine function is heavily distorted
as seen below. I do not believe that this is due to the design on a protoboard and its parasitic capacitances.
What could I do to obtain a more beautiful sine output?
Thank you in advance.
