Noise Jitter influences

017_jitter_noise : Noise Jitter influences

Requires: SmartSpice & Smartview

Minimum Versions: SMARTSPICE 4.6.5.R

A simple 9 Stage inverting Ring Oscillator is used with an external N element noise source injected through a capacitor to show jitter sensitivity in the ring oscillator output. The input deck input deck contains .TRAN NOISE and .MEASURE analysis.

Rubberband the C2 device capacitance [cap] parameter to see the influence of injecting a different noise level on the performance and EYE diagram of the node v(x20.cn1) and you will see with no external noise source waveforms and with the injected noise waveforms visable.
