Hello all, can someone give me a hand importing a bjt transistor pnp? I downloaded the file which is in .txt ( see the file ) At this point i dragged it into ltspice and what appears is this: also when i right click on the name, the ''create symbol'' doesnt really appear, what can i do?

I've been trying to write a Python code that recreates the simulation of a simple NPN BJT in LTSpice, but i have been having difficulties on finding the exact equations they use in the software, i have stumble upon some equations that is used in the gummel poon model, but the results in the simulator never matches exacly on the code i create based in these equations. Does anyone know where i can find these equations ?

Hi All - been looking at the specs for the new Lattice Avant platform as I liked the MachXO product for the few low-end designs that I've done. However, it doesn't really seem that Avant has that many differentiating factors against Xilinx and Altera, especially the Agilex 5 which seems like a nice family. Has anyone that designs at the mid-end made the switch over? Why/Why not?

You have the CKE and CKP bits here. Look at the datasheet pictures to see what combo gives the needed SPI mode. Use pictures instead of words to understand what's needed. It is confusing because the early documents were wrong. https://microchip.my.site.com/s/art...-and-phase-reword-for-PIC18F-microcontrollersThink about what SPI mode you need , then set the controller bits for that mode. In general:In SPI there is only one clock edge that matters to the receiver.

At Embedded World 2025, Taoglas showed off six new multi-band GNSS modules for future IoT-GNSS applications. While GNSS technology is fairly mature, the integration of amplifiers, filters, receivers, and antennas can pose a challenge to designers, especially as devices continue to shrink in size. To address these limitations, Taoglas’s newest front-end modules offer a highly integrated RF front end in a small package.
