006_lstb_stability_diff : Differential Stability analysis

Requires: SmartSpice & Smartview

Minimum Versions: SMARTSPICE 3.17.26.C

This example input deck will allow you to look at the following results.

The .LSTB analysis is used in common and differential mode

  • phase_margin(deg)
  • gain_margin(db)
  • phase_margin_freq(Hz)
  • gain_margin_freq(Hz)
  • minfreq
  • loop_gain_at_min_freq(db)

are calculated, and cx1,cx2 etc. files are written out, which contain gain as a function of frequency, and the CMDMPROBE technique is demonstrated.
