If done correctly the DC will be subtracted and the result will be no DC offset. Add a 9V battery (or an extra DC supply) with a voltage divider on the other terminal that has nearly the same value as the DC offset that was added to the sine wave.

Using the function generator add a DC offset to your sine wave input on the non-inverting terminal. To test the differential input, do the following: Circuit Setupĭesign an instrumentation amplifier using the LM324 or LM348 Op-Amp with a gain of 10 V/V (See MultiSim file on D2L). Using the provided thermistor, build a circuit using the LM386 that turns on a fan whenever the temperature gets too hot (simulate this by holding your finger over the thermistor). With the speaker attached at the 40 V/V gain setting plot the output on the scope and explain what you see. Next, send the LM386 output to a speaker. Plot the input and output on the scope for both gain settings. The potentiometer should produce a gain of 30 V/V when turned all the way one direction and 40 V/V when turned all the way the other direction. Input a 500 Hz 200 mV peak to peak sine wave to a LM 386 IC that has a gain adjustment from 30 V/V to 40 V/V. Problem 6ĭesign a 2 kHz sine wave oscillator circuit using the LM324 or LM348 Op-Amp. Integrating a square function produces a triangle function. The integrator circuit, outputs the integration of the input signal. Adjust the duty cycle of the square wave and comment on how it affects the triangle wave and show a screen shot.

Using the square wave from the function generator as the input, build an integrator circuit using a LM324 or LM348 Op-Amp that will convert the waveform to a triangle wave. Using these and additional data points sketch the bode magnitude plot (dB vs Hz). To prove the design meets the specifications do at least 5 screen shots of Vi and Vo at 5 Hz, 150 Hz, 2 kHz, 10 KHz, and 150 KHz. $$gain = 20log(\frac)=29.54dB$$ĭesign an Op Amp filter that has a gain of 12 V/V +/- 0.5 V/V between 150 Hz and 10 kHz and less than 1 V/V gain for frequencies less than 5 Hz and greater than 150 kHz.

YOU MUST use dual supplies and have an output that is symmetrical about the y axis. Either a non-inverting or inverting amplifier configuration can be used. The TA must verify functionality by adjusting the potentiometer to max and min settings. When the potentiometer is turned all the way counter clockwise the gain should be 15dB and when it is turned all the way clockwise the gain should be 35dB. Make the input voltage a 200 mV peak to peak sine wave input at 500 Hz. Circuit Setupįind a potentiometer in the lab and design an Op-Amp circuit using the LM324 or LM348 that will have an adjustable gain from 15dB to 35dB. The unity gain bandwidth can be determined from Figure 5 of the datasheet. Compare the value you measure to the spec. Increase the frequency until the output is at the value you calculated. Using the finite gain equation, set A0 = 1 and calculate the output voltage with the resistor ratio and input voltage amplitude you used. Circuit Setupĭesign an experiment to measure/calculate the unity gain bandwidth AND the gain-bandwidth product of one of the channels of a LM324 or LM348 Op-Amp. The slew rate can be determined from Figure 7 of the spec. Design an experiment to measure the slew rate of one of the channels of a LM324 or LM348 Op-Amp and represent the slew rate in the units of V/μs.
