Question
This project had to use an opAmp that had a Rload of 1K ohms and had to have a voltage of 2V peak. Also, the gain had to be approximately 10. I made this project on a real breadboard and it worked perfectly. Now I have a few questions left which are listed below. Please answer all three questions and show work:
a) What determines the high-frequency response and at what frequency is the 3 dB down point for your project?
b) What is a reasonable power supply voltage?
c) What is the input impedance of an amplifier?
In the schematic, Vin is an AC voltage source with 0.2V

1) High frequency response can be determined by junction capacitance of differntiadi amplifiers of op-amp.
2)reasonable power supply of 5 v is enoufe but we need to apply dual power supply.
3)if we consider op-amp as ideal then input impedance is 560 K ohms.
