By … WebJan 31, 2024 · 1 Here I have a Colpitts oscillator: The feedback fraction is C1/C2. However during an LTSpice simulation if we set C1 = C2 the oscillation is not underdamped. How is this possible since we will get a feedback fraction of 1 and the voltage gain of a BJT is always less than 1 so the oscillation must die out? voltage analog oscillator Share Cite

The Colpitts Oscillator Complete tutorial on circuits

WebA Colpitts is an electronic oscillator. Importantly, this oscillator uses inductors and capacitors, which contribute to an LC circuit. The functioning of this oscillator involves the use of transistors, op-amps, Field Effect Transistors, and valves. Also, it is an electric harmonic oscillator with lots of applications and advantages. The 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 … See more The basic configuration of the Colpitts Oscillator resembles that of the Hartley Oscillator but the difference this time is that the centre tapping of the tank sub-circuit is now made at … See more The advantage of this type of capacitive circuit configuration is that with less self and mutual inductance within the tank circuit, frequency … See more The emitter terminal of the transistor is effectively connected to the junction of the two capacitors, C1 and C2 which are connected in series and act as a simple voltage divider. When … See more As with the Hartley oscillator, the Colpitts oscillator uses a single stage bipolar transistor amplifier as the gain element which produces a sinusoidal output. Consider the circuit below. The frequency of oscillations for a … See more Webfigure 1.3 (a). Hartley Oscillator use two series-connected coils and a single capacitor. The feedback can be through an inductive tap, see figure 1.3(b). Clapp oscillators preferred over a Colpitts circuit for constructing a variable frequency oscillator. In a Colpitts Oscillator, the voltage divider contains the variable inconel shortage
