I have to design and do the layout of an LC and a Ring VCO (both at 5Ghz), but I have stuck with the layout. The output does not oscillate; it just has a steady value (the dc analysis however is consistent with the schematic). I attach some screens of the layout of the VCO. I use thick and big in width metals (top level) for the signal. For ground and supply lines, I use first level of metal and maximum width. I use a lot of connectors at the nodes; will this result into a problem? Should i use less connectors? I do not have a lot of experience with physical design as an undergraduate student. Does anyone have any suggestions that might help?
Oscillators that do not oscillate in a simulator
you need a copy of Ken's book:
