Learn how to minimize noise in operational amplifier (OP AMP) and analog-to-digital converter (ADC) circuits by calculating, simulating, measuring, and filtering noise. The course covers topics such as understanding different types of noise, simulating noise with and without filters, analyzing noise in resistors, and comparing simulation results with real measurements. The intended audience for this course includes electronics engineers, circuit designers, and anyone interested in improving the performance of OP AMP and ADC circuits. The teaching method involves a combination of theoretical explanations, practical examples, simulations, and comparisons between simulated and real-world results.
