Hi, everyone
I am completely stuck with this question and the assignment is due on Wednesday. I am studying Electrical Circuits at Curtin University as part of my Mechatronic Engineering course and need help with Op-Amps.
Q1.The op Amp in the following circuit is supposed to be ideal. There is no initial energy stored in the capacitors.
I have looked everywhere for explanations on how to get the transfer function but cant find anything useful. Our lecture has not covered the topic yet and i cant afford the textbook. Could you please help me out.
Thanks in advance,
Will

Q1.The op Amp in the following circuit is supposed to be ideal. There is no initial energy stored in the capacitors.
- Find the expression for the transfer function:
- Let R1 = R2 = 1 kΩ, R3 = 500 kΩ, R4 = 270 kΩ and C1 = C2 = 316 pF, plot the amplitude of H(j2πf) with respect to the frequency f. What could we say about this circuit?
- If Vin(t) = 100cos(1000*pi*t) mV; find and plot the expression of Vout.
- ZL in the circuit is an AC motor, which it can be modulated by a resistor Rm = 10Ω in series with an inductor Lm = 500mH, (i.e. ZL = Rm + j w Lm ) .
- Calculate the total power transferred to ZL.
- Find the power developed by Vin. Comment the results obtained in last two questions.
- The power supply of the op Amp is Vcc = 10 V. If the amplitude of Vin has been increased by a factor ten, replot Vout.
- Using passive RLC circuits (in series and in parallel), find two equivalent circuits to H(s).
I have looked everywhere for explanations on how to get the transfer function but cant find anything useful. Our lecture has not covered the topic yet and i cant afford the textbook. Could you please help me out.
