* Use realistic square wave with rise time/ fall time 50n Should get graph showing large negative current spikes indicating backwards current flow in diode as shown below in graph of simulation. Use this netlist as source, then "run", then "plot vout vin". Here is a diode circuit for investigating the reverse recovery time. *vvvvvvvv Included SPICE model from 2N3904.mod vvvvvvvv * provides advanced spice netlisting capability. Here is a spice netlist for a 2-transistor negative feedback amplifier. Also google spice and go to links like this.ĭiode 1N4007 *vvvvvvvv Included SPICE model from 1N4007.mod vvvvvvvv Spice Stuff Spice Stuff: diode and transistor models netlist examples for feedback amplifier, reverse recovery time of diode, and opamp amplifierĬlick for a tutorial example and gschem with opamp.
