Capacitive Voltage Divider as an AC Voltage Divider
Consider the two capacitors, C1 and C2 connected in series across an alternating supply of 10 volts. As the two capacitors are in series, the charge Q on them is the same, but the voltage across them will be different and related to their capacitance values, as V = Q/C. ...
Principle of Colpitts Oscillator The Colpitts oscillator is based on the principle of LC resonance. It comprises a combination of capacitors (C 1 and C 2) and an inductor (L) connected in a feedback loop. The LC …
You insert a tuning capacitor at the top (left side of the diagram) to tune. Just like you tune an old-fashioned radio. This is so because the entire structure of the magnetic loop is so small compared to the wavelength of the signal you are dealing with, unlike dipole and/or other e-field type antennas.
Capacitive coupling, also known as crosstalk, is a major component of noise on both inputs and outputs of dynamic gates. Wires adjacent to a domino gate may have capacitance to …
Voltage Follower Circuit Diagram | Capacitor-Coupled Voltage …
Capacitor-Coupled Voltage Follower: When a voltage follower is to have capacitor-coupled input and output terminals, the noninverting input must be grounded via a resistor, [see (R 1 ) Fig. 14-12]. As discussed, the resistor is required for passing bias current to the noninverting input terminal.
Coupling capacitors make the two systems of strong and weak currents coupled and isolated by capacitors, provide high-frequency signal paths, prevent power frequency current from entering …
1 Multi-capacitance systems and mutual capacitor Of an ac network, a linear capacitor C, when supplied with an ac voltage source across its terminals, is described as i = C (dv /dt) [], which characterises the i − v relationship between its two terminals or between a single conductor and somewhere at infinity in system; where C is …

Non-contact voltage sensors based on the principle of electric field coupling have the advantages of simple loading and unloading, high construction safety, and the fact that they are not affected by line insulation. They can accurately measure line voltage without the need to connect to the measured object. Starting from the principle of …
The resistances R 1, R 2 and R E form the biasing and stabilisation network. The emitter bypass capacitor offers a low resistance path to the signal. Without this capacitor the voltage gain of each stage would be lost. The coupling capacitor C C transmits a.c. signal but blocks d.c. transmits a.c. signal but blocks d.c.
