how to calculate tuning range for vco

hai
may i know how to find tuning range for LCvco and center frequency is 1/(2*pi*(LC)^(1/2))
thanks in advance

A LC circuit consists of the inductor L and capacitor C. A part of the capacitor is the varicap diode having a specified range of capacitance controlled by the tuning voltage.
From the above you can calculate the tuning range.

can you elaborate how to calculate varicap diode cap and you mentioned from the above make it little bit clear


thanks

I can elaborate but you did not indicate any real values. It seems to me it is time for you to read some basics on VCOs and LC circuits. Try ARRL Radio Amateurs' Handbook to start.
