Hi

How can I have VCO with phase wrapping, either 1 or 0.
If I have Verilog-a model of VCO and I set fc (free running frequency) at 0 and Kvco at lets say 100e6, while the input voltage of the VCO is a pulse (between 0 and 1).
Does it mean that I have a vco with phase wrapping, either 1 or 0?
Do I have a oscillation with frequency of 100e6 while input is 1 and phase freezing when input is 0?

Thans for any help
