Transfer Function Analysis
The TF line defines the small-signal output and input for the dc small-signal analysis.
.TF <out_var> <in_src> |
out_var
Is the small-signal output variable.
in_src
Is the small-signal input source.
The simulator computes the dc small-signal value of the transfer function (output/input), input resistance, and output resistance. For the first example, the simulator would compute the ratio of V(5, 3) to VIN, the small-signal input resistance at VIN, and the small-signal output resistance measured across nodes 5 and 3.
.TF V(5, 3) VIN
.TF I(VLOAD) VIN
