Inverting Amplifier R2 W VEE R1 w OP ArmpA 3 Vout R3 VCC L1 inma C1 C2 바 Feedback network Figure 4: Colpitts Oscillator Using a 741 op-amp with VCC = 15 V, determine the following parameters of a Colpitts oscillator of Figure 4 to have a 20 kHz oscillating frequency: a) Ci; b) Ct; c) L; d) Ri; and e) R2. Assume that R1 is greater than twelve times the impedance of the capacitance of Ci and R2 is much greater than the product of the minimum loop gain and Ri. Select C2 as 1000 pF and C1 eleven times the value of C2.
