LTspice Lesson 4d: Generate Waveforms used in Electric Circuits: PWL FILE
LTspice Lesson 4c discussed creating a waveform using a handful of discrete points, but by using PWL FILE as shown below, large number of points can be easily imported into LTspice simulator to generate more sophisticated waveforms. In this lesson, we … Continue reading
LTspice Lesson 4c: Generate Waveforms used in Electric Circuits: PWL
by Kashif Javaid Piecewise linear voltage or current source is very interesting and can be used to create arbitrary waveforms. Basically you define points (tx, vx) to draw out the precise waveform. For times before t1, the voltage is v1. For … Continue reading

LTspice Lesson 4b: Generate Waveforms used in Electric Circuits: PULSE
LTspice has various options to generate a custom pulse for circuit simulations. Generating a pulse is done through an independence voltage or current source as shown below: Pulse minimum voltage, maximum voltage, delay before the pulse start, rise time and … Continue reading
LTspice Lesson 4a: Generate Waveforms used in Electric Circuits: SINE
Kashif Javaid Instead of cutandpaste of LTspice help file as some of LTspice tutorials on the internet has done, I think best way to learn nitty and gritty of this tool is to solve a circuit by hand, predict it’s … Continue reading
LTspice Lesson 3: Transmission lines part 1
Kashif Javaid In this lesson we will focus on a single element Lossless Transmission line (Tline) as shown in Figure 1. Lossless T line simulation will be introduced here. One of the goal of these lessons are to give out … Continue reading

LTspice Lesson 2: Node Voltage and Mesh Current Analysis using LTSpice
LTspice command: .op Node voltage and Mesh current are methods that systematically calculate voltages and currents in a circuit. Although LTspice calculate voltages and currents by using sophisticated network theory, but nonetheless, it can be useful to match the node … Continue reading
