zopt()

Returns optimum impedance for noise match

Syntax
y = zopt(gammaOpt, zRef)

Arguments

Name	Description	Range	Type	Default	Required
gammaOpt	optimum reflection coefficient	(-∞, ∞)	complex		yes
zRef	reference impedance	(-∞, ∞)	real, complex	50.0	no

Examples

a = zopt(Sopt, 50)

Notes/Equations

Used in Small-signal S-parameter simulations.
This complex measurement produces the optimum source impedance for noise matching. gammaOpt is the optimum reflection coefficient that must be presented at the input of the network to realize the minimum noise figure (NFmin).
