RFPA design simulation PSS Vesus QPSS

[whlinfei]

Hi,

I am trying to simulate RFPA using spetreRF.
I understand that there are two PSS simulation method. PSS and QPSS.
since QPSS does not assume of periodicity, does it mean that it is more accurate than PSS?

Thanks.

Best Regards,

You will use PSS for PA's..
Or Harmonic Balance..

Completely wrong.

PSS is an expansion by single frequency basis while QPSS is an expansion by multiple frequency bases which have no common divisor frequency each other.

Generally, only one frequency is involved for PA application.
So PSS should be your choice.

Wrong.

HB is one of analysis method for "PSS".
See my appends in https://www.edaboard.com/threads/194649/

In Cadence Spectre, HB-PSS and Shooting-Newton-PSS are available as "PSS" analysis.
In Cadence Spectre, HB-QPSS and Shooting-Newton-QPSS are available as "QPSS" analysis.

In Agilent ADSsim, only HB-PSS is available as "PSS" analysis.

In Agilent GoldenGate simulator, Harmonic-Balance, Time-Shooting and Time-Balance algorithms are available as "PSS" analysis.
