Could you please tell how to calculate propagation delay in LTSPICE for CMOS circuits. Or is there any other software for calculation of delay of CMOS circuits? Thank you.
Hello all, When I run a simulation on LTSpice it generates a graph. By doing File->Export I can get the numerical values in a text file. However this doesn't help me much. For example I want to find the crossing point of Vout and Vin. I see they cross at some point in graph but can't tell...
Re: Why do we use "AC1" while doing ac analysis in LTspice ? what does AC1 mean? Whenever I use LTspice to make a plot of frequency response of a filter the signal generator always says "AC1" which is its AC reference amplitude.
It is an undocumented feature in LTspice. Resistors Behavioral Resistors Create a behavioral resistor by right-mouse-button clicking on its Value field and edit its value to read: R=<expression>. This feature is undocumented, but is considered permissible to use.
It is well-known that rotating a resistor in LTspice by 180 degrees will change the reference current direction through this resistor, and the voltage across and current through this resistor will appear to be 180 degrees out of phase. I don't think this has anything to do with the so-called...
Hi, I am running a LTSpice (v 24.1.7) transient simulation using TLV271 op-amp. I first ran a sim with a single op amp. The sim ran OK. When I ran the sim on my ckt, the simulation is continuously running for more than half an hour and not ending. I tried by relaxing the gmin to half the...
Hi, I've been working with LTspice, and found that many times the simulation get very slow, in fact - not useable. Can anyone help with that? I've tried several solutions (see below) but it didn't work. Please see attached two simulation project examples: 1. LED driver (LT3474) with and without...
The opamp needs a power supply. The simple circuit you show with no capacitors needs a dual-polarity power supply. Its an LTSpice Ideal OPA, [bit like a 741.] Doesn't require power rails. The *.lib was missing from his layout
