003_1GHz_amplifier : Tuned 1GHz Amplifier Schematic

Minimum Required Versions: Gateway 2.12.8.R, SmartSpice 3.16.11.R

This schematic example ( amplifier_schematic.png ) shows a 1GHz tuned amplifier designed using the VBIC level=5 NPN bipolar model.

The control file ( tuned1GHz_AMP.ctr) displays the specifics of the .AC statement and the VBIC model .

The OUT node is marked with both phase and gain markers, which specify these save macros into the input file:

.save VDB(OUT) .save VP(OUT)

Running the simulation produces the gain and phase ( waveforms.png ) outputs as shown. To split the waveforms to appear on separate charts, right click and choose Split All/Selected Charts in SmartView.
