In LTspice, insert the ±10 mV AC injection voltage source and injection resistor and label nodes A, B, and C as shown in Figure 2. The AC voltage source valueSINE(0 10m {Freq})sets the 10 mV peak and sweeps the frequency. The user can play with peak sine values between 1...
This article provides open-source LTspice® simulation circuits to answer key questions: (a) will my system pass EMC testing, or do I need to add mitigation techniques? and (b) how immune is my design to noise from the external environment? Why Should I Use LTspice for EMC Simulation?
In LTspice, an arbitrary behavioral voltage source can be used to create an AM waveform. AM waveforms can be demodulated using a multiplier followed by a low-pass filter. A simpler (and lower-cost) approach is to use a leaky peak detector, i.e., a peak detector with...
download my schematics Charger0.asc and my model library SUB_LIB.txt to your simulation working directory and play with it. If you are not using LTspice, you need to manually enter the
independent noise source is useful. For example, a noise source may be part of a sensor. No standard signal source is available for noise analysis. To that bold statement, I add “that I know of and is documented!” If you know of one built into LTspice, please let us know in ...

How the LC tank circuit works is that an inductor and capacitors are in series with each other. In order to charge up the circuit, we need a DC power source. The DC power source charges up the capacitor. Once the capacitor is charged up, now if we turn off or take away the DC po...
The best source for an IBIS model is from the manufacturer itself; however, it is still possible for the user to create IBIS models. This article introduces a way to create the most basic IBIS model derived from a SPICE model using LTspice. The following sections u...
“Amplifying AC Signals with Large DC Offsets for Low Power Designs”). In most applications, it is preferable to get as much gain as possible at the first stage as this helps in improving the referred to input (RTI) noise of the following gain stages in the signal chain. This article ...
