1.   Demo kit Transmission Line:

 

a)     Parameters:

 

Name

Description

Unit

Default

Type

Type of transmission line(M0, M1, M2 or M1+M2)

nil

M1

Width(w)

Width of the transmission line

um

20

Length

Length of the transmission line

um

100

Inductance

Associated inductance of the transmission line

pH

41.924

Offset1

offset at pin 1, for Thick metal only

nil

None

Offset2

offset at pin 2, for Thick metal only

nil

None

 

b)    Range:      

                  Type0 (M0) ;           M0 transmission line  ; Width, w=(5 to 50 um) ; Length, l = 5um to infinity 

                  Type1 (M1) ;           M1 transmission line  ; Width, w=(5 to 50 um) ; Length, l =   5um to infinity 

                  Type2 (M2) ;           M2 transmission line  ; Width, w=(5 to 50 um) ; Length, l =   5um to infinity 

                  Type3 (M1+M2) ;     M1+M2 transmission line  ; Width, w=(5 to 50 um) ; Length, l =  5um to infinity           

 

2.   Notes:

 

a)     These transmission lines are based on schematic MLIN models (with proper MSUB definitions).

b)    For general inter connections, use either Type 1 or Type 2 lines. Type 3 lines carry higher current (as their thickness is more).

c)     Type 0 line is generally used to connect capacitors.

d)    Available both in schematic and layout with synchronization.

 

 

3.   Model accuracies:

Type = tline1; Width, w = 10 um ; Length, l = 150 um ; Inductance = 90.9099pH

                   At 20 GHz the Phase difference is 4.677 degrees.
