1. I am designing a LC VCO using TMSC 0.18 and I noticed there are no pads in the library. I need to submit the design for fabrication. I want to know is there any way I can do the layout of the pads and I will be thankful if there is any tutorial for doing layout of pads.
2. The minimum value of inductor I am using is 2.3nH in TSMC 0.18

I am designing a inverter driver to drive a 20-50pf capcitance. i use the
cascade of inverter structure (each is two times than the last one). But the delay
is too large to damage the timing.
So is there other method to do this things?

The layout seems to be fine but add some vias under the case to connect ground of the SAW filter.Add at least 6-8 small vias under the package..( if you're using double or multiple layer PCB)
In addition to, increase just a little bit the copper pour pattern around input and output pads to prevent the parallel capacitors which aren't wanted..
