Hello, I'm trying to construct a simple Class A Common emitter Colpitts oscillator. The Electronics book that I have tells me that I need to compute the Rcoil of the inductor. To do that, I need the Q factor of the inductor at 1 MHz, which is the frequency I'm trying to generate. How do I get the Q in the first place? I do have an LCR meter which gives me what I think is the series resistance, the inductance and the Q, which it says is around 1.12 (at 1Khz), of the inductor. It also has a 120Hz option. Is this Q something I can use to compute the Q at 1MHz? I need the correct value of Q to run the Colpitts oscillator at 1Mhz. Any help, including formulas or circuits to compute Q, would be much appreciated. Thanks, rsr_life.
