Title: Accumulation-Mode Varactor
Post by yhq0413 on Mar 24^th, 2008, 2:20am

I simulate the varactor using spectreRF
I sweep the voltage sources connected to G node and S/D node respectively.
The capacitance is different.I do not know why?
what is the difference between the G and S/D?
which node should be connected to the Vtune?why?
thanks in advance
