Create an Op AMP based circuit that converts a 2 Vpp 350 Hz Square wave (Vin) into a 4 Vpp 350 Hz Sine Wave (Vout) that is in phase with the square wave. Show this using Multisim (please attach multisim picture).

Expert Solution

WE WILL USE A 3 POLE RC FILTERS NETWORK TO PRODUCE A SINE WAVE FROM A QUARE WAVE .THE CIRCUIT IS BASED ON CHARGING AND DISCHARGING PRINCIPLE OF CAPACITORS.WE WILL USE AN OPAMP NON INVERTING CONFIGURATION NETWORK TO AMPLIFY THE OUTPUT VOLTAGE .THE R AND C VALUES WILL DEPEND ON THE INPUT FREQUENCY GIVEN BY THE RELATION 2*PI*R*C*F=1 .

AS F= 350 HZ

RC =(1/350)

CHOOSING C =0.1 uF

R=4.54 kilo ohm.

output of rc network

AS SHOWN IN THE DIAGRAM ABOVE REQUIRED GAIN IS 6.2

SO 1+ RF/RIN =6.2

RF/RIN =5.2

CHOOING RIN =2 K

RF=10.4 K

FINAL AMPLIFIED OUTPUT

THUS FINAL OUTPUT IS 4 V PEAK TO PEAK SINE WAVE

*** IF YOU WANT THAT ALL THREE SIGNALS OSCILLATE OBOUT ZERO VOLT THEN USE A -1 TO 1 V INPUT SQUARE WAVE.

Suppose we have a 10-Hz sinusoidal voltage source, vin(t). Draw the diagram of a circuit that clamps the positive peaks to −4V. The circuit should be composed of ideal diodes, dc voltage sources, and other components as needed. List any constraints that should be observed in selecting component values. Be sure to label the terminals across which the clamped output waveform vo(t) appears.

Describe the conditions under which an op-amp circuit will oscillate. Provide a technique to avoid undesirable oscillation. Explain why the gain-bandwidth product (GBW) is limited for any amplifier, and why GBW is constant for a fully compensated voltage feedback op-amp. If a fully compensated op-amp has GBW = 4 MHz, and its closed-loop amplifier circuit has gain (closed-loop gain) = 100, what is the loop gain at 100 Hz?
