WebThe Colpitts oscillator uses a capacitive voltage divider network as its feedback source. The two capacitors, C1 and C2 are placed across a single common inductor, L as shown. Then C1, C2 and L form the tuned tank circuit with the condition for oscillations being: X C1 + X C2 = X L, the same as for the Hartley oscillator circuit.. The advantage of this type of … WebBarkhausen`s condition (with all its restrictions) applies to active LC oscillators as well as to RC oscillators. In both cases, the loop gain DESIGN value for steady state conditions must be unity.
