Dear friends,
I simulated a simple RF circuit and do the pss and save all. As everything is all right except the power. Why the power plot displayed to me is much smaller than I estimated? Which one should I trust?
Enclosure is the plot and my circuit is specified by a supple voltage of 1.2V and a tail current source of 530u.
Vdd*Idd = 0.636mW = -1.97dBm
The Cadence tutorial indicates that the power plot's DC power is the power consumption, that is -6.56dBm = 0.22mW
Please help me as my report deadline is coming!
Thank you all for your time.
