You are to design and simulate a simple op amp Circuit Diagram Only a couple resistors and capacitors are needed to make a simple audio amplifier. The chip has functions for gain control and bass boost, and it can also be turned into an oscillator capable of outputting sine waves or square waves. The LM386 is a type of operational amplifier (Op-Amp). Operational amplifiers have a basic task.
The opamp circuit using transistors appears reasonably linear (reduced distortion) as pointed out in the scope picture listed below. The upper waveform is the ramp input from a function generator, and the bottom waveform is the inverted output of the op-amp having a 50 ohm load.

1.1 Simple op amps Objective. In this lab we introduce the operational amplifier (op amp), an active circuit that is designed with certain characteristics (high input resistance, low output resistance, and a large differential gain) that make it a nearly ideal amplifier and useful building block in many circuit applications. Offset voltage: The DC voltage that, when applied between the input pins, will cause a DC output voltage of zero. If both inputs were grounded, the output voltage of the op-amp would not be zero. Slew rate: The time taken for the output to change for a given input.Specified as V/mS. Equivalent input noise voltage: The noise performance of the op-amp. An ideal voltage source is placed in series This project is a brief introduction to build a simple signal processing circuit. It uses two LM741 Operational Amplifier ICs (opamp). It will accept a signal from the function generator and will couple it via a first op amp in a buffer or impedance coupler configuration. Then the resulting signal is fed into an inverting amplifier.
An op-amp has two inputs, an inverting terminal (labeled โ-") and a non-inverting terminal (labeled โ+"). And has a single output. The first input is called inverting because the output voltage is inverse of the voltage applied at the inverting input, times the gain of the amplifier circuit.If we apply the signal to the non-inverting input we get the same signal on the output, times gain.

A simple voltage follower. The input can vary from -12 to +12, starting at +2.5 V and seeing how far positive and negative the op amp will recognize. The LM741 would not recognize an input voltage lower than 1.8 V or higher than 4.4 V. The LM741 is used in many schools because it is a good example of the problems with op amps. The identical 741 op-amp can also be used in a circuit which does not depend on an external signal source (AC mains hum). The 741 op-amp is used in a high-frequency oscillator circuit that operates around its peak frequency in this very unique proximity sensor device described below. The internal feedback capacitor of the 741 op-amp restricts
