Normally they are accounted for correctly within the subcircuit but, for different cases, the main thing that should be remembered is the order of the pins (not necessarily digits). E.g.: .subckt NMOS

Helmut, Thank you. I originally wanted to use nmos, but I didn't find Ctrl-right mouse to change the prefix, so I did it the hard way, but didn't know to set the Prefix and Value.in the ASY. I also

Hello Brian, You forgot to set two values in the symbol(.asy). Prefix:X Value:BSH103 LTspice assumed a hierarchical schematic due to of these missing attributes and failed because you don't have a

All, I uploaded BSH103_test.zip. I am attempting to make the BSH103 subckt work. The simulation seems to rn, but emits a warning which I recognize as being about the pin names in the ASY file, but I

All, I uploaded a file called BSBH103_test,zip. I am attempting to use the subckt file for the BSH103. The run seems to work, but there is a warning that I have been unable to decipher. I recognize

Getting the breadboard to work involves paying more attention to the data sheet and app notes than to the model. The LT1241 series is intended to be pin-compatible with UC3842 series. RL

Hill" winfieldhill Hi Win, How's it going? I don't have a particular varactor/varicap that I'm fond of using. Recent chips have used an on-board MOS device as a varicap (at ~5GHz). In the past the

Hello Theunis, It would be bad practice to store something in the installation folders of LTspice. Copy the symbols(.asy) and the model file(s) in the folder of your schematic. You will then reach the

Thanks Helmut Really did not expect an answer so fast, Thank you. Is there a short document some where explaining how to get the UC3842 model into the spice lib. Couldn't find symbol(s) error: ? thank

Hello, At least one more chance, but I assume the model from analogspiceman mentioned in my previous answer is better. https://groups.yahoo.com/neo/groups/LTspice/files/%20Examples/SMPS/UC3842/

Helllo, Take a look here. https://groups.yahoo.com/neo/groups/LTspice/files/adventures_with_analog/my%20model%20files/

Morning guys Is there a LTSpice model for uc3842 family. I have been using LTSpice to simulate LT3751 and LT3748 simulations works 100% but when built either one on PC-board or breadboard I don't get

There is one in the standard component menu for diodes in LTspice. I tend to use that one for applications that need something in the range of 2-10pf. Jim Wagner Oregon Research Electronics
