APPLICATION NOTE 023
TOLERANCE IN SURFACE MOUNT VARACTOR DIODES
The ability to specify tolerance in the nominal capacitance has been added to selected models in the
Modelithics Non-Linear Diode (NLD) Model Library in order to emulate the variation typically specified in
manufacturer data sheets. The feature will be included in additional models in future library releases.
This application note briefly reviews this new capability and provides suggestions on how it should be
used.
A sample simulation schematic from Agilent's Advanced Design System is shown in Figure 1. Included in
the schematic is the VAR_TSH_TG1A_005 model for the Toshiba P/N 1SV280 varactor diode. The
model parameter used to specify the capacitance tolerance is Cap_tolerance
