Ground OPAMP An operational amplifier or op-amp is simply a linear integrated circuit (IC) having multiple terminals. The op-amp can be considered to be a voltage amplifying device that is designed to be used with external feedback components such as resistors and capacitors between its output and input terminals. It is a high-gain electronic voltage amplifier with a differential input and usually a single-ended output. An operational amplifier is basically a three-terminal device consisting of two high impedance inputs, one called the inverting input (-) and the other one called the non-inverting input (+). The third terminal represents the operational amplifier's output port which can both sink and source either a voltage or a current. Non-Inverting Amplifier The non-inverting amplifier is one in which the output is in phase with respect to the input. The feedback is applied at the inverting input. However, the input is now applied at the non-inverting input. The output is a non-inverted (in terms of phase) amplified version of the input. The gain of the non-inverting amplifier circuit for the operational amplifier is easy to determine. The calculation hinges around the fact that the voltage at both inputs is the same. This arises from the fact that the gain of the amplifier is exceedingly high. If the output of the circuit remains within the supply rails of the amplifier, then the output voltage divided by the gain means that there is virtually no difference between the two inputs. Non-Inverting Amplifier Circuit Diagram RESULT The basic op-amp circuits of non-inverting amplifiers were designed, set up, and output waveforms were obtained in a CRO. The gain obtained is Non-inverting amplifier: Gain = ........ 15V R100k Model Graph Observation Table Input Frequency F kHz Input voltage (p-p) Vi A Vo V Gain Av=Vo/Vin
