Summary

My main focus is on designing analog circuits, especially for prototypes. I handle the entire process from concept development, component selection, simulation, schematic, layout, generating manufacturing data, ordering prototype production, to testing and modifying prototypes. I use my Orcad Professional license with PSpice and my lab for this. Early in the project, I'm happy to travel to the client for a few days. Later on, this should be limited to what's necessary. For me, analog circuits also include RF and optoelectronics. My YouTube channel focuses on switched-mode power supplies: [link]
