Spice selbst ist kommandozeilenbasiert, aber es gibt eine Vielzahl an Programmen, die graphische Simulationsumgebungen für Spice bereitstellen. LTspice Dieses Skript konzentriert sich auf die Simulation mit LTspice4, welches von dem Halbleiterherstel-ler Linear Technology entwickelt wird. LTspice ist eine kostenlose Spice-Simulationsumgebun Overview. Among his several important contributions to circuit theory and control theory, engineer Hendrik Wade Bode, while working at Bell Labs in the 1930s, devised a simple but accurate method for graphing gain and phase-shift plots. These bear his name, Bode gain plot and Bode phase plot. Bode is often pronounced / ˈ b oʊ d i / BOH-dee although the Dutch pronunciation is Bo-duh add spice lines that set the inductance L and switching frequency fs values; these are needed for evaluation of the averaged model in DCM. The CCM-DCM1 averaged switch model may encounter numerical difficulties near D = 0 that can cause LTspice to diverge or give incorrect results. It is highly recommended that your PWMavg model employ a minimum duty cycle of at least Dmin=0.02. 2. DC Sweep.

bode(sys) creates a Bode plot of the frequency response of a dynamic system model sys.The plot displays the magnitude (in dB) and phase (in degrees) of the system response as a function of frequency. bode automatically determines frequencies to plot based on system dynamics.. If sys is a multi-input, multi-output (MIMO) model, then bode produces an array of Bode plots, each plot showing the. s| =1, making a Bode plot of the magnitude of the output voltage gives us the same graph as a Bode plot of the transfer function.) The first way to get decibels is to change the probe. Back in the circuit diagram, select the voltage problem and delete it. Then choose a dB probe from the PSPICE menu item (Pspice Wolfgang Bengfort (Dipl.-Ing. Elektrotechnik) unterrichtet nach 10-jähriger Berufstätigkeit in der freien Wirtschaft seit 2003 die Fächer Elektrotechnik und Informatik an berufsbildenden Schulen Predicting the efficiency of an application is vital to evaluating design trade-offs of a switching mode power supply. Two useful tools, the .step and .meas commands, can be used to calculate and plot efficiency over a range of load currents.To evaluate efficiency, clearly label your input and output voltage net as IN and OUT, respectively The first step to creating a netlist is to label the nodes in your circuit diagram with names that SPICE will accept (numbers or words are fine, but the number '0' is always reserved for the ground node). We have chosen to use words to name the nodes as shown on page one. Each circuit element has a specific syntax for how it should appear in the netlist (see the 'cheat sheet'). For the.

Bode Plots in LTspice. One of the most interesting analyses that LTspice can perform is frequency analysis, also known as AC analysis. We can see its capabilities with a simple low-pass filter. For an AC analysis, we need to define one AC source. Various parameters can be configured for a voltage source in LTspice, but amplitude is enough for our purposes. We'll also configure four. Click SPICE Directive on the toolbar to display Edit Text on the Schematic screen. Make sure that the SPICE directive is selected, enter the dot command syntax (.tf V(OUTPUT) V1 in this case), and click OK to place the created dot command. Simulation/Analysis result. 1. Click Run on the toolbar to run the simulation. The simulation time varies depending on the. Probing the OUT node will plot the frequency response of the filter, clearly showing roll of above 1kHz. The phase response of the output with respect to the ac signal source is also plotted on the right hand y-axis. If we want to magnify a certain area of the plot, move the crosshairs to the desired part of the plot, left click the mouse and, holding it down, drag it over the area to be. To render the Bode plot, SPICE requires a lot of special attention. In fact, some users simply skip SPICE-based AC loop analysis and instead try to deduce control loop robustness from the load step transient response alone. However, this is sort of like skipping a patient's blood pressure measurement, relying instead on the patient's pulse. There are a variety of approaches to performing.

Bode Plots. Incidentally, the graph output produced by this SPICE computer analysis is more generally known as a Bode plot. Such graphs plot amplitude or phase shift on one axis and frequency on the other. The steepness of a Bode plot curve characterizes a circuit's frequency response, or how sensitive it is to changes in frequency The SPICE directive that you see near the circuit basically asks LTspice to simulate the frequency response in the 100Hz - 1.6MHz frequency span with a resolution of 1000 points per decade. By clicking the simulate button we obtain the following graph of the frequency response.

A Bode plot is convenient as it shows the magnitude and phase of the transfer function in the frequency domain and in the steady state (after all transients have decayed); this allows you to see how the filter affects both important aspects of input signal behavior in a pair of plots. To enable Bode plot visualization, click on Simulate → probe manager. Make sure the Complex Function.

Bode-Diagramme 31.10.2011 Sven Riester 1 Bode-Diagramme Selten misst man ein vorhandenes Zweipolnetzwerk aus, um mit den Daten Amplituden- und Phasengang zu zeichnen. Das kommt meistens nur vor wenn Filter abgeglichen werden müssen oder man die berechneten Eckdaten eines Hi-Fi-Verstärkers am realen Objekten kontrollieren will. Viel eher wird man in der Entwurfphase anhand einer. 1.3.2 Übertragungsfaktor, Bode-Diagramm 8 1.4 Verlustleistung und Eigenerwärmung 12 1.4.1 Thermischer Widerstand, thermische Zeitkonstante. 12 1.4.2 Zulässige Verlustleistung und Wärmeabfuhr 15 1.4.3 Zulässige Verlustleistung bei Impulsbetrieb 19 1.5 Halbleiter 21 1.5.1 Elektronen und Löcher, Bandschema 21 1.5.2 Halbleiter im thermischen Gleichgewicht 25 1.5.3 Stromtransport 32 1.5.4.
