hi,
I am in the process of designing a DPLL through cadence(180nm process) . I completed a 200mHz center frequency VCO for a PLL using a current starved oscillator. Now i am trying to design a DPLL based on a 2.4GHZ balanced NMOS VCO. So far i wasnt able to generate any oscillation and i am starting to think that i am missing something in the concept.
Does any one have materials or tutorial in the design of a VCO based on a balanced NMOS configuration..
It will be really appreciated thanks!!!!
