Question

Figure Q3(b) shows a phase shift oscillator circuit. Given the feedback gain:

i Determine an equation for frequency of oscillation

ii Calculate the value of capacitors, C, if the output voltage is equal to
5 sin 3?? ?? and resistor, R is equal to 100 ??Ω.

iii Calculate the open-loop gain, A, in order to generate an oscillating signal.

iv Determine the value for ??1and ??2 in order to generate an oscillating
signal. You may refer to the Appendix in page 5 and 6 for the commercial
value of resistor.
