8.4 Simplifying calculations
This is the fourth of nine videos in the TI Precision Labs – Op Amps curriculum that addresses operational amplifier noise. In the previous training we did a comprehensive noise hand calculation for a very simple op amp circuit. In a real-world circuit, these hand calculations can be long and complex. In this training we will provide several rules of thumb which can be used to simplify noise calculations by identifying the dominant source of noise and ignoring noise sources that do not make a significant contribution. Identifying the dominant source of noise will give you insight into how you can quickly and effectively improve your system’s noise performance.
