This is Part 2 of a series of three articles that provideLTspice®EMC and signal integrity simulation models. In “How to Get the Best Results Using LTspice for EMC Simulation—Part 1”, we provided LTspice simulation tools for power supply components, conducted emissions, an...
The polarity of the current must be inverted to measure the value of the current flowing into the buffer while sourcing it with AC voltage. When measuring the output buffer capacitance, the only change that must be made from Figure 15 is that the AC source must be ...
o You will need to fill in the correct values, based on the resistive sensor you used • Click Simulate -> Run -> Go to the DCop pnt tab -> Click ok • Simulation screen will pop up, click on the node you want to measure. (V out) ...
the first option is to consider an electrolytic capacitor. In some applications that the ripple current is very high, electrolytic capacitor will not work anymore as its ripple current is smaller. In this case, film capacitors are chosen as they are having very high...
off Q1 and in turn Q2 ( and I think the other cap makes the short delay between the two ( where the cap is loaded) i would think the cp would become laded to more as 1V. Then current is higher as I thought or your led had a higher Vf ( i took 2V like most red leds are...
So amplitude is just a measure of the DC power supply level. The next parameter we can adjust is the frequency of the sinusodal waveforms. There will be a series of sine waves created by this circuit and we can adjust what frequency these signals will have by the selection of the inducto...

So maybe we should call it a “current-to-voltage converter for power-supply-current-delivery-monitoring applications” (abbreviated CTVCFPSCDMA). Perfect. Why? There are various situations in which you might want to measure the current consumed by your design. Maybe you want to d...
This article, part of AAC’s Analog Circuit Collection, presents a straightforward circuit that allows you to measure temperature with little more than a diode and a BJT. If you’ve ever spent a Saturday afternoon browsing through the plots and performance curves in a diode datasheet, you’ve...
The high-pass filters are used to measure supply and return supply line noise. These voltages are measured across 50 Ω resistors, as illustrated in Figure 5 and Figure 6.1 In a real lab, this voltage is measured using an EMI receiver. LTspice can be used to probe the noise voltages...
