Unformatted text preview: EECS 70LB Spring 2011 Lab 2: Operational Amplifier (Op Amp) Circuits Reading from Chapter 7 of Scherz: 7.2: Theory 7.3: How an Op Amp works 7.4: Negative Feedback Summary: There are 2 circuits for this lab. Components Op Amp (741 series). This is one of the most popular op amps. It is based on bipolar transistor technology and a portion of the circuit will be covered in EECS 170C. 2-1 Inverting Amplifier (Fig. 7.11, pp 543, Scherz) Vout R1 OUT 1 + 3- 2 V+ 4 V- 11 LM324 V4 R2 Fig 3-1. Inverting Amplifier R1=10k , R2=100k , RL=10k ; Connect Vs to 12 V. Procedure: (1) Connect the circuit as shown in Fig. 3-1. Use a 10 kHz sinusoidal signal with amplitude of 0.5 V as the source. Display both input and output waveforms on the oscilloscope. Increase the amplitude of input voltage continuously until the output waveform is clamped. When this happens, increase Vs from 12 V to 15 V....
