Title: VCO Duty Cycle
Post by bhupendra on May 26^th, 2004, 5:56am

we're working on 400 MHz VCO Design. We've used current starved type VCO. This works fine and gives proper duty cycle with all corner cases except FF 0 3.7V
and FF 85 3.7V. Its duty cycle is varying. So how can we proceed with this issue.
