EXP

Exponential factor.

EXP=0: Constant Q

EXP=1: Constant R

 

 

 

 

 

TEMP

Local temperature

Notes

1. The model is described by the following:
,

 where w=2pf, and f is the operating frequency.

2. If Q is not specified, then the capacitor is assumed ideal, i.e., Gd=0.

3. The exponential factor, EXP, acts on Q according to the following equation:
where fref is the reference frequency for Q. So, when EXP=0, Q=constant, and when EXP=1, the conductance Gd in the equivalent circuit is constant.

Netlist Form

CAP:NAME n1 [n2] C=val [Q=val F=val] [EXP=val] [TEMP=val]

Netlist Example

CAP:CAP1 1 C=5PF

Constant Q, Gdµf:

CAP:CAP2 1 2 C=5PF Q=75 F=2GHZ

Qµf, constant Gd:

CAP:CAP3 1 C=5PF Q=75 F=2GHZ EXP=1

Q(f)=Q(fQ)(fQ/f)EXP:

CAP:CAP4 1 2 C=1PF Q=200 F=1GHZ EXP=1.6
