Analysis of Operational-Amplifier Inverting and Non-inverting Amplifiers in Remote Lab

In this paper, performance analysis of Opamp inverting and non-inverting amplifiers using Remote Lab is presented. Remote lab system has the feature of conducting experiments on Opamp Amplifiers with different voltage gain. Remote lab system is built using Arduino ATMEGA-2560, National Instrument’s (NI) Analog Discovery kit and other circuitry. User has the freedom to apply input signal of desired amplitude and frequency. Opamp parameters like slew rate and unity gain bandwidth, can be evaluated. Paper describes the process of determining Opamp amplifiers like closed loop gain, 3-dB bandwidth, and phase and gain margin. Paper also presents analysis report of Opamp amplifiers conducted remotely.
