Find Resonator/Oscillator Capacitance/Inductance at 1 MHz

[AskTheGenius]

hi guys,

can someone tell me the capacitance and inductance for a 1 MHz resonator/oscillator

thanks,
your neighborhood genius

http://en.wikipedia.org/wiki/RLC_circuit" It's under resonance frequency.

You'll have to start with an assumption. Assume one of the following three, and you can solve for the others:

C
L
X of C and L

At resonance, Xc = XL = 2*pi*f*L = 1/2*pi*f*C

You could try these:

16 uH... 1592 pF

24 uH ... 1061 pF

32 uH ... 796 pF

Try to download the following program:

I set the reactance to about 200 ohms and let the program work out suitable L and C values.
Watch the units.

Then the hard part is finding suitable inductors. The ferrite rod antenna in transistor radios resonates at 1 MHz with about 200 pF.
