TV Noise Options

The TV Noise and Periodic Transfer Function (PXF) analysis options are listed in the table below. The TV Noise and PXF option values can be changed with a .OPTIONS statement in a netlist.

Note

The TV Noise option values cannot be changed in a schematic design.

The syntax for the .OPTIONs statement is:

.OPTIONS tv_noise.option1=val1 [tv_noise.option2=val2 ... ]

Use the prefix tv_noise. to apply the option value only to time-varying noise analysis but not to other tools that recognize the option. See Analysis-Specific Options for a listing of options that are used by more than one Nexxim analysis.

**TV Noise and PXF Analysis Options**
Option	Default Value	Description
abstol	1e-12	Absolute error tolerance for currents (Amp)
freqaxis	absin	Output results versus the input frequency, the output frequency, or the absolute value of the input frequency. Only for PXF.
fund	None	Steady state analysis fundamental frequency (or estimate for autonomous circuits).
iprobe	None	Input RF port, current source, or voltage source for small-signal input. For a port, Nexxim computes the noise figure and conversion gain in Volts (in the sense of available power)
linearsolver_restarts	1	Maximum linear solver restarts
max_linearsolver_iterations	20	Maximum number of iterations for linear equation solver
maxsideband	None	Maximum sideband for PXF
noise_output		Output nodes where noise should be computed in noise analysis. No noise factor or conversion gain is computed for these outputs
oprobe	None	Output port, current source, voltage source, resistor, or current probe for small-signal output.
probe	None	PXF computes every transfer function to the specified probe component
pxf	false	Enable PXF analysis
refsideband	None	Coefficients for calculation of the input frequency
relharmnum	None	Specify a single relative harmonic number
relharmvec	None	Specify a list of relative harmonic numbers
saveallsidebands	no	yes=save all sideband results
sidebands	None	List of relevant sidebands
ss_analysis	hb	Select hb or osc to compute the steady-state values
ss_maxk	None	Maximum number of harmonics at each frequency in the steady-state calculations
ss_tones	None	List of frequencies to use in the steady-state HB calculations
reltol	1e-3	Relative error tolerance for currents and voltages (dimensionless)
tstab	None	Initial stabilization time. Can be used to change the starting phase of the HB algorithm
hb.auto_refine_solution	no	For power sweeps, yes=increase number of harmonics as power increases
hb.method	hb	hb=standard HB calculation. shooting=HB method for strongly nonlinear circuits
hb.trim_tol	0	Harmonics voltage tolerance. Harmonics less than trim_tol after the initial guess are pruned. 0=no pruning. Mainly for internal use.
