Question

The ac equivalent circuit for a Colpitts oscillator is given as shown What is the frequency of oscillation if gm = 10 mS, βo = 100, RE = 1 kΩ, L = 6 μH, C1 = 20 pF, C2 = 100 pF, and C3 = infinity? Assume that the capacitances of the transistor can be neglected A variable capacitor C3 is added to the circuit and has a range of 5–50 pF. What range of frequencies of oscillation can be achieved? (c) What is the minimumtransconductance needed to ensure oscillation in part (a)? What is the minimum collector current required in the transistor?
