Re: How to simulate PA efficiency in cadence spectre simulat
In Cadence 5.141, directly PAE may be used in PSS analysis.Otherwise, Each input and output should have curent probe to measure the currents and of course with node voltages PAE and other important parameters can be simulated.
But better way is to ADS or RFDE, because in these simulators, to simulate some important parameters is easier by inserting formulas, equations etc.
For DC power H0 should be used.And general power equations must be as..
Power=0.5*Real(V(node)*Conjg(I(brach))) or
Power=0.5*Real(Conjg(V(node))*I(branch))
In ADS, Harmonic index can be defined as V[0] or as generalized by definition V[n]
I'd personally prefer to use ADS or RFDE for Power Amplifiers with Harmonic Balancesimulator engine.
