A TEK scope plot of two waveforms, exported as a single CSV file. Do you simply strip them, to separate columns and process as two PWL files? Recall doing it before, a few years ago, but damned if I

Hello! I tried to simulate a +9...+30 Vin, +3.5...+4.2 Vout dc/dc converter using LTC3765 & 66 chips. While it simulates nice using default LT settings as in jigs directory, any attempt to use lower

I'm not really sure if LTspice would be the best program for you. Arduino is a programmable microcontroller and requires programming before it will do anything. Search on google for "fritzing".

Let me save you a lot a trouble. The domestic ring main is not a high speed data circuit. If you take data at 1Mbps then 1 data bit is just 1 micro second duration. This is very short compared to any

Can anyone tell me where to find a schematic for the arduino pulser. Also i need to find a potiometer spice and symbol that works. Thanks

His model seems to run OK (on my computer) as long as it stays below slew-rate limiting. As soon as the output slew rate hits +/-10V/us and starts flattening out, that's when it starts getting the

Hello, You can ignore the warnings about "Length shorter ...". All the Microchip opamp models make a lot of trouble with convergence problems in LTspice. Sometimes I can find a solution, sometimes

Those are just warnings. I see those a lot. Level 1 MOSFETs were around in 1973 when SPICE was brand new, and MOS channel lengths as small as a micron were uncommon. Microchip's models have 2 micron

Please leave schematic files as files, and upload them to the Temp folder. Pasting them into an email makes for extra tedious work. Your simulation severely over-stresses the op-amp. Its absolute

please give me the simple working model?

yes, in no problem )) problem is no work model parameter

By examining this model, there is a potential problem, but I think it doesn't actually cause an error in LTspice: .SUBCKT MCP63x 1 2 3 4 5 > ... Notice how the name of the subcircuit (MCP63x) does not
