SimRF. . Application Note. Sheila P. Werth, Stephen J. Bitar, & Sergey N. Makarov. ECE Dept. WPI, Worcester, MA. July 5. th. 2011 . 1. Outline. Concept . of a noisy operational amplifier. What is the Inverting Mode ?. The op-amp can be connected up in various ways or . modes. .. What it does depends on how it is connected up.. When connected up in the inverting mode, it changes positive voltages to negative voltages. It may also make them larger..
