Figure 14.17 (a) An RLC circuit. Electromagnetic oscillations begin when the switch is closed. The capacitor is fully charged initially. (b) Damped oscillations of the capacitor charge are shown in this curve of charge versus time, or q versus t.The capacitor contains a charge q 0 q 0 before the switch is closed.
The two basic properties of a capacitor are that it can store electric charges and that it passes higher-frequency AC currents more easily. However, in high-frequency ranges, the capacitor begins to reveal a different side. This is because the subtle inductive component within the capacitor becomes more dominant, and the capacitor alone begins to behave …

The circuit can work using a number of different op amps. Considering that output-coupling capacitor C2 is required to generate both low and high frequencies, its value must be suitably adjusted to some intermediate value, for example it can be 0.01 µF, unless of course the user is prepared to change this capacitor in addition to L1 and C1.
Hence employing 220 nF capacitors provides an functioning frequency of around 100 Hz, and 2.2 nF capacitors would deliver oscillation at around 10 kHz. The circuit will perform satisfactorily over a frequency range of less than 1 Hz to more than 20 kHz. C2 is a stabilisation capacitor and C3 offers output D.C. blocking.
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 oscillator circuit.. The …
