Using LTspice for EMC and Signal Integrity This is Part 2 of a series of three articles that provide LTspice EMC and signal integrity simulation models. In How to Get the Best Results Using LTspice fo
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...
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) ...
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...
Because of large capacitance, the simulation time is set to 1 second and captured the last 1mS data. This allows everything to settle in a steady state in order to measure power. That took my computer 6 hours to complete. For other types of measurement, 2mS simulation time is good enough...
of 120Vrms at 60Hz. This is the same as the above circuit but redrawn and simulated in LTspice. LTspice is a freeware circuit simulation tool from Linear Technology. If you want to learn on how to do simulation on LTspice, read the articleLTSpice Circuit Simulation Tutorials for Beginners...
An FPGA can easily generate such waveforms to the gate drivers. However, that does not clarify your requirements; what current and voltage do you want to measure? For example, do you want to measure the instantaneous current and voltage during the time each of the I...
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...
