Op amp as a Voltage follower Voltage follower is a negative feedback op-amp amplifier circuit. It acts like emitter follower configuration of transistor based amplifiers. They provide unity gain to the applied input signals. Unity gain means the output voltage will be exactly equal in magnitude with the input voltage. Fig. 1: Circuit Diagram of…
Non inverting amplifier using LM 324
Some or the other time we need to amplify DC and AC voltage. This Non inverting amplifier circuit can solve our purpose. It can amplify voltage to high [[wysiwyg_imageupload::]]extent. This project can be used anywhere where we need amplification of voltage. The dependency of the output with the inverting and non-inverting pin can be simply explained as below,If the inverting pin is high compared to other pin, the output is negativeIf the non-inverting pin is high compared to other pin, the output is positiveKeep on reading to find out how mathematical formulas in involved in the process of non-inverting amplifier circuit, how the circuit is made and how it works.
