s_stab_circle_center_radius()

Returns the center and radius of the source stability circle

Syntax
s_cr = s_stab_circle_center_radius(S, Type)

Arguments

Name	Description	Range	Type	Default	Required
S	2-port S-Parameters		complex		yes
Type	Type of parameter to return	["both"|"center"|"radius"]	string	"both"	no

Examples

s_cr = s_stab_circle_center_radius(S)
returns a 1X2 matrix containing center and radius
sCirc = expand(circle(s_cr(1), real(s_cr(2)), 51))
returns data for the source stability circle
s_radius = s_stab_circle_center_radius(S, "radius")
returns the radius

Notes/Equations

Used in Small-signal S-parameter simulations
If the argument Type is not specified, the function returns complex data. Although radius is of type real, the values are returned as complex. Therefore, when using the returned radius, use the real part. To obtain the radius as a real number, set Type to radius .
