Question 4 2points A Common Base Colpitt Oscillator Shown In Figure 4 Operates At 1ghz Assume The Bjt Is Ideal Re 1 (100.53 KiB) Viewed 9 times
help me solve this Question 4 (2points): A common-base Colpitt oscillator shown in Figure 4 operates at 1GHz. Assume the BJT is ideal, RE >>ZC2, CB →∞, L = 125 nH, RL = 2.4KOhm and C₁ =1.5C2. Vcc=6V, B-100. Find: a. The oscillation equation of this oscillator. Find the required capacitance C1 and C2 b. The required transconductance (gm) of transistor so that the circuit can oscillate. Find Re and RB of the oscillator. C. d. -- END --- RB CB Figure 3 VCC www RE C₂ Figure 4 RL
