Chapter 4
Introduction to Spice Noise Analysis
In Chapter 3, we had used a hand analysis on a simple op-amp circuit. In this chapter, we use a circuit simulation package “TINA Spice” to analyze op-amp circuits. A free version of TINA Spice (TINA-TI) can be downloaded from the Texas Instruments website (http://www.ti.com, type in TINA under search). TINA Spice can do the traditional types of simulations associated with Spice packages (e.g., DC, transient, frequency domain analysis, noise analysis, and more). Furthermore, TINA-TI comes loaded with many TI analog macromodels.
In this chapter, we introduce TINA noise analysis and show how to prove that the op-amp macromodel accurately models noise. It is important to understand that some models may ...
