Hello,
I should design an oscillator just consists of inductors and capacitors . the circuit should not have any resistors.
also, It has 4 MOSFETs instead of Not Gate. the lenghth of each inductor should be low, but the number of them are high. (as the schemes have shown below)
I designed and tested in every situation that I thought. The problem is that there is not resonable scheme after the simulation.
Any help will be appreciated.
Please see attached.

L=0.25 mH
length of L=12.5 mm
C=0.25 pf
No. L or C=52
VDD=10 v
(W/L) in Mosfet=(25/0.5)
but the plot was shown nothing!!
