Please add the line below to the subcircuit. .model Dbreak D. Below is the subcircuit with the extra model line for Dbreak. .SUBCKT NCP431 K A ref. D_NCP431_D7 K NCP431_N29971 Dbreak. WebSep 22, 2005 · The sw.sub is in the \lib\sub directory, and the sw.asy is in the \lib\sym directory. The sw.asy attributes seem to reference the sw.sub correctly, and the Netlist Order seems to agree with the picture and the node numbers in sw.sub. Both files look OK, but LTSpice always comes up with

WebMay 19, 2024 · Extract from LTspice Help The symbol's attributes can be overridden in the instance of the symbol as a component in a schematic. For example, if you have a symbol for a MOSFET with a prefix attribute of 'M', it's possible to override the prefix to an 'X' on an instance-by-instance basis so that the transistor can be modeled as subcircuit instead. WebJul 19, 2024 · Why would it clip the negative voltage any more than it would clip the positive voltage. Ground has no polarity. The capacitor removes the dc bias at the output of the op amp so the capacitor output has a DC average of zero volts. For that to happen, the output waveform must equally go above and below ground, as you observed.
