Hello everyone,
I am working on LogAmp detector development using ADS tool.
Used topology:

There are the uncompromises among Transient (Trans), Harmonic Balance (HB) and Envelope (ENV) simulations when I try to observe output time domain response as following plots:
![](http://i28.photobucket.com/albums/c222/nghichnham/HB.jpg)
The uncompromising points are:
1. Trans simulation introduces very different output steady level (compare with ENV and HB)
2. Trans and ENV simulation show opposite equilibrium-reaching process
Could anyone give me comment on the differences?
Thanks alot for help
