Mit dem Parametric Sweep in LTspice lassen sich Bauelementeparameter als Variablen deﬁnieren. To do this, first click on the simulate button and then click on the edit simulation command. The DC Sweep analysis generates output like that of a curve tracer. In addition, LTspice can use auxiliary units as shown in the following table. LTSpice muss wissen, was berechnet werden soll. With AC sweep, you can calculate the small-signal response of a circuit. W A VE Write Selected Nodes to a . A DC Sweep is a type of simulation that allows you to vary the voltage or current of a specified device. DC Sweep. die Spannung einer Spannungsquelle) verändert wird. It increments the voltage or current of a selected source in predefined steps over a range of values. In the above menu we need to enter the following parameters. Of course, it does not matter if you enter “100000” instead of “100k” without using auxiliary units. This performs a DC analysis while sweeping the DC value of a source. An optional second source can also be used to run a nested sweep. SINE 3. This video shows how to analyze a simply op-amp amplifier on MAC OS X LTSpice.
