Hi all,
I have design a double balanced Gilbert cell mixer.
In ADS, the output IFp and IFn are 180 deg out of phase.
Then I simulate in Cadence, the problem is that the IFp and IFn signals are in phase. I think that is the reason why the conversion gain is smaller than 0 dB.
I have spent couple of days but I cannot figure out the reason. Please help! Thank you so much.
