60 GHz VCO, still ongoing 🙂
• Done (more or less):
â—¦ CCP
â—¦ Varactor banks
â—¦ Inductor plus guard ring
â—¦ Buffer fet connections
• To do:
â—¦ Buffer loads (microstrips)
â—¦ CCP current mirror
â—¦ RF pads
â—¦ Biasing, biasing everywhere!
â—¦ Figure out about the placement of density tiling inside the top cell (HALP!)
Simulations tells me that it oscillates at around 60GHz with a FTR of 4.5% (taking into account most of the parasitic loading sans inductances)
