Analysis and Measurement of Intrinsic Noise in Op Amp Circuits: Part V - Introduction to Noise Measurement by Art Kay, Senior Applications Engineer, Texas Instruments Incorporated
In Part IV we used TINA SPICE to analyze noise in op amp circuits. The example circuit used for TINA SPICE analysis was also used in the hand analysis example from Part III. The result from hand analysis and TINA SPICE closely matched each other. Here in Part V, we introduce the different types of equipment used for measuring noise with specifications and modes of operation pertinent to noise measurement discussed. Although specific models of equipment are considered, the concepts can be applied to most equipment. In Part VI we will show real-world examples of how the equipment is used to measure the circuits described in Parts III and IV.
