What will I learn?
The Linear Integrated Devices (LID) Course shows you how to design clean, low-noise audio preamps from the ground up. Learn power supply decoupling, grounding, EMI/RFI control, stage-by-stage signal chain design, and smart component selection. Practice bench testing, troubleshooting, calibration, and performance calculations so your builds deliver stable gain, low distortion, and reliable real-world performance.
