I tried to create an LTspice simulation of Jim Thompson's headphone amp (5/21/14 5:16 PM post). I got the supertex models from supertex.com and the TL082 model from TI. When run it produces the error message: Fatal Error: Port(pin) count mismatch between the definition of subcircuit "tl082" and instance: "xu2" The instance has more connection terminals than the definition. What have I g...

Hello, I am trying to simulate a buck and a boost converter using Christophe Basso's generic PWM models (in LTSpice) for voltage mode controlled and current mode controlled switched mode power supplies. These models have an integrated PWM generator and power switch. These models can be found here: http://cbasso.pagesperso-orange.fr/Downloads/IsSpice/Final%20models.zip (alternati...

Hi, what has recently happened to my Spice? Below is a simple resistor divider and this is the R2 voltage: https://i.postimg.cc/SxPYBV2c/spice.png Switching between solvers doesn't make any difference.

Here are the documents for a short-circuit protected constant current supply for making silver ions and other uses. The current can be adjusted from 100uA to 20mA. The compliance range is 320V. The polarity swap is on a separate pcb not shown here. The zip contains the LTspice ASC and PLT files, and the Diptrace schematic and pcb files. The pcb is hand wired for the moment, so the n...

I've been using the Analog Devices Spice model in LTSpice to model the AD734 running with a current output - see Figure 25 on page 13 of the Rev E AD734 data sheet http://www.analog.com/media/en/technical-documentation/data-sheets/AD734.pdf When running a roughly 15kHz sine wave through the device, the positive current output limits at something between +200uA and +280uA.

Hello, I have a resistor R5 with some current flowing through it. It is possible to plot I(R5) by simply selecting the resistor. But is it possible to plot dI(R5)/dt? If yes, then how?
