Re: ADS
ADS2006 provides simulators that enable you to simulate circuits and RF systems. it contains a wide variety of simulators that can be used to simulate many types of circuits, with certain types of simulators applied to certain types of circuits.
it provides these main simulations:
DC
AC
S-parameter
Harmonic Balance
Large-signal S-parameter (LSSP)
Circuit Envelope
Transient/Convolution
RF System Budget Analysis
it is a very powerful software, but still needs effort to learn.
