Title: A question about noise simulation using spectre
Post by chip on Jan 24^th, 2007, 7:42am

When using spectre noise simulation,the option for the output, What is the difference between "Voltage" and "Probe"
Thanks a lot.

With voltage, you give a pair of nodes and it takes the output to be the voltage between those nodes. With probe you give a component, and Spectre uses the component to determine the output. If you specify a voltage source or iprobe as the probe, it takes the output to be the current through that component.
