Furthermore, in a second-order canonic oscillator, if the two capacitors employed are grounded this is preferable from the point of view of IC implementation [2], [3]. As a consequence, two-grounded-capacitors-based SRCOs using numerous single active building blocks (ABB) have been reported in the literature [4]-[21].

Chassis ground: In a system like a computer or radio, it is impractical to connect common 0V points to the earth ground, so these connect to the chassis, casing, or housing of the device. Ideally there is only one common point. In devices with a danger of shock, for example a kettle or toaster, the housing will also be connected to mains earth.
The capacitors to ground form a low-pass filter for the lines they''re connected to, as they remove high-frequency signals from the line by giving those signals a low-impedance path to GND. See this question.

Question: Two 5 uF capacitors are connected between terminals as shown. One terminal is grounded and the other is held at 100V. What is the charge on one (no both) of these capacitors? Three point charges are arranged so that two of them are inside a spherical Gaussian surface of radius 20 cm, as shown. The third charge is outside.
The two capacitors are one electrolytic capacitor (polarised) (typical value 6.8uF)and the other ceramic non-polarized (typically 100nF). The electrlytic capacitor has high current capacity so that it can carry large spike current when …
Decoupling capacitors connect between the power source (5V, 3.3V, etc.) and ground. It''s not uncommon to use two or more different-valued, even different types of capacitors to bypass the power supply, because some capacitor …
Suppose one plate of the capacitor is grounded which means there is charge present at only one plate. We know that the potential across the capacitor will be 0, i.e., V=0. And capacitance of the Capacitor will be C=Q/V. C=Q/0 implying C=∞. So it means that the capacitance of a grounded capacitor is Infinite.

The two capacitor paradox or capacitor paradox is a paradox, or counterintuitive thought experiment, in electric circuit theory. [1] [2] The thought experiment is usually described as follows: Circuit of the paradox, showing initial voltages before the switch is closed. Two identical capacitors are connected in parallel with an open switch between them. One of the capacitors …
Two capacitors connected positive to negative, negative to positive are connected in a loop. Whether they are considered parallel or series depends on how other circuit elements are connected to them.
There isn''t anything special - it''s ground and those two capacitors connected to ground and are no more in series than R2 and the NPN transistor''s emitter. So, C1 provides some initial phase shift by interacting with the high compliance output of the collector. In effect, the collector can be regarded as a voltage source in series with several ...

A capacitor acting as an HF short circuit must have low lead and PC track inductance, so each supply capacitor must be located very close to the two terminals of the IC it is decoupling. It is also important to choose capacitors with low internal inductance–usually ceramic ones. Many ICs contain circuitry which generates HF noise on their supply.
Note that all terminals connected to ground are likewise connected to each other. But we do not show this connection "directly" on a schematic. Now we can try to analyze your circuit. The capacitor charging current is flowing in this way: And during the charging phase, the capacitor voltage is rising from 0V to 3.3V.
Figure 1: Botth sections, A and B, may be on the same PCB with separate ground planes (e.g., analog and digital). The diodes and the capacitor between the planes limit potential differences due to ground bounce, etc. Broken lines inside boxes 1 and 3 indicate ground referenced, non-symmetrical inputs and outputs.
Hi, It''s just to get rid of any static charges, when the board is inserted into the chassis. This is because the edge is going to be the first bit that touches the chassis, and the capacitors have physically been placed with one end close to the chassis, and the other end connected to the PCB ground.

$begingroup$ But the product is not connected to earth ground. Your answer sparked a hypotheses though: because chassis is not grounded, RF noise may be coupled to other elements on PCB (like a photodiode output, for example). To prevent this, the capacitor forms a short circuit to signal ground for RF signals. Could this be correct ...
And no current flows through the capacitor of phase C. ... or alternators is directly connected to the ground.

$begingroup$ I have done a design with an isolated DC/DC switching device, and you should not connect the ground with a wire. However, placing a capacitor to interconnect the two grounds helped to mitigate noise problems due to a non-optimal layout. $endgroup$ –
