011_hbt_tran_noise : Transient Noise for HBT device
Requires: SmartSpice & Smartview
Minimum Versions: SMARTSPICE 4.6.5.R
This Transient Noise example input deck with .TRAN NOISE and .MEASURE shows how to get a feel of noise influences on the transient response of your circuit by rubberbanding cc[cap], rb[res] and rc[res].
