PAE Graph

Xxy · May 12, 2021

Hi,

I had designed a CMOS Power Amplifier using Cadence. Attached is my simulated PAE graph, from the graph can see that the maximum PAE is not met at Pin> 0dBm. Is it any suggestion to solve it? Thanks.

Hi,

Please follow the recommendations that memers gave at your other thread: https://www.edaboard.com/threads/how-to-make-pae-graph-smoother.397839/post-1710955

Still the step size is too coarse.

Hi,
I've changed smaller step size, but the PAE curve still didn't have much changes. But this time, my question is the x-axis (Pin), I need to get maximum PAE which stay at Pin> 0dBm.

show us what you did.

We just see the curve consisting of maybe 7 points. Surely not enough..
