.TF — Find the DC Small Signal Transfer Function

This is an analysis mode that finds the DC small signal transfer function of a node voltage or branch current due to small variations of an independent source.

Syntax:

.TF V(<node>[, <ref>]) <source>
.TF I(<voltage source>) <source>

Examples:

.TF V(out) Vin
.TF V(5,3) Vin
.TF I(Vload) Vin
