The IR Engineer Education Institute is hosting a seminar that covers the journey from the fundamentals of key components like transistors, MOSFETs, and op-amps to analog circuit design through LTspice exercises, as well as noise measurement and countermeasures.

While analog circuits using transistors and op-amps play a vital role in wide-ranging applications such as amplification, power supply, and sensing, they are also prone to issues like failing to achieve desired characteristics or sensitivity to noise due to lack of understanding of operational principles or oversight of design conditions. Proper circuit design, checking behavior via simulation, and identifying and addressing noise sources are keys to improving design quality and practical application.
