resistance equation
Many references say negative resistance of colpitts oscillator can describe the following equation.
-R = -gm/ ω^2/C1/C2 (gm :: trans conductance of FET)
However,negative resistance is also proportional to the ratio "C1/C2".
Does anyone tell me how to develop the expression for the exact negative resistance?
Thanks,
