I find that the harder I work, the more luck I seem to have.

Dept of Electronics & Communication Engg INVERTING, NON-INVERTING AND DIFFERENTIAL AMPLIFIERS USING OP-AMP EXP.NO: 01 DATE: AIM: To design the Inverting, Non-Inverting and Differential Amplifiers using Op-amp IC741 and test their performance. APPARATUS REQUIRED: S.NO COMPONENTS RANGE QUANTITY 01 EACH 01 EACH 02 01 1. IC 741 2. RESISTORS 3. DIGITAL TRAINER KIT 1KΩ, 33KΩ 10KΩ, 100 KΩ. --- 4. SIGNAL GENERATOR (0-3)MHz 01 5. CATHODE RAY OSCILLOSCOPE (0-30)MHz 01 6. CONNECTING WIRES --- FEW THEORY: Op-amp in open-loop configuration has a very few application because of its enormous open-loop gain. Controlled gain can be can be achieved by taking a part of output signal to the input with the help of feedback. This is called as ClosedLoop Configuration. The three basic types of closed-loop amplifier configuration are: 1. Inverting amplifier. 2. Non-inverting amplifier. 3. Differential amplifier. The entire configuration can be operated with either AC or DC input. INVERTING AMPLIFIER:If the input signal is applied to the inverting terminal through an input resistance, a part of output is feedback to the inverting terminal through feedback resistance Rf and the non-inverting terminal grounded, then the configuration is said to be Inverting Amplifier. It provides 1800 phase shift or polarity reversal for the given input. The circuit closed-loop voltage gain is Avcl Rf . R1 4
