What will I learn?
The Linear Integrated Devices (LID) Course teaches you how to design clean, low-noise audio preamps from scratch. You will learn about power supply decoupling, proper grounding, controlling EMI and RFI, designing the signal chain stage by stage, and selecting the right components. You will also practise bench testing, troubleshooting, calibration, and performance calculations to ensure your builds provide stable gain, low distortion, and reliable performance in real-world situations.
