LTspice Lesson 4e: Generate Waveforms used in Electric Circuits: EXPonential
LTspice provide a built in exponential waveform generator. This can be very helpful to generate arbitrary exponential pulses to simulate special systems such as surge protector or ESD modeling. In this lesson, we will understand all the parameters that are … Continue reading

Tour du Mont Blanc 2019
A travelogue by Faraz Faheem Tour du Mont Blanc Day 1: The Union (London > Geneva > Chamonix) After witnessing Pakistan beat South Africa at Lords Cricket Stadium and a sumptuous buffet at Royal Nawab the previous night, the London … Continue reading
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
