![]() ![]() The second is PHDEG(V(out)), which asks for the phase in degrees. ![]() The first expression is DB(MAG(V(out))), which asks for the magnitude in dB. This tells the simulator to give us more resolution in the frequency domain, at the cost of taking more time to run the simulation.Ĭlick on the node name "out" and observe that two expressions are added to the simulation settings Outputs list: This tells the simulator that V1 is our driving source, and it should show us the small-signal response relative to changes in that source. Let's have the simulator generate the Bode plot.Ĭlick Simulate at the bottom of the window to open the simulation settings panel, and then click Frequency Domain:Ĭlick the Input field and an autocomplete appears. Great! We've finished drawing an RC low-pass filter. Press N and click to insert a node name label at the top of the capacitor. Press G and click to insert a ground node at the bottom of the voltage source: Flip through the screenshots below to learn how to display a Bode plot in just a few clicks.įrom the toolbox, click and drag a voltage step source, a resistor (press R to rotate horizontal), and a capacitor onto your schematic:ĭrag from component endpoints to connect the circuit with wires: ![]() Filters and Frequency Response (Bode Plot)Īmplifiers and filters require thinking in the frequency domain. ![]()
