1) Pick your frequency
2) find a suitable inductor with high Q at that frequency, remembe that inductor Q rises with frequency, and is givein by: QL = 2*pi*f*L/R, where R is the effective resistance of the inductor (parasitic resistance)
3) After choosing L, use the equation F=1/2*pi*√((C1 + C2)*L), and rearrange to:
C1 + C1=(1/2*pi*F)²*1/L, to get a value of C1+C1
4) Use the above equation, and C2/C1 > 1/Av, where Av is the voltage gain of the transistor amplifier. Allow a little margin to account for resistive losses.
5) Iterate through the procedure and adjust C and L values to get a reasonable value for L, which makes QL large, but keeps the physical size of the inductor reasonable.
6)Simulate your design at each iteration, using the equation in step 2 to calculate a value of R to connect in series with the inductor. The trick here is to allow the sim to run long enough so that oscillations get started. Just keep experimenting.
7)Once you're happy with your values, and the simulation is producing correct results, then build and test your design.
