Unified Theory of the Capacitance Behavior in LDMOS Devices

This article reviews and provides physical insights into the anomalous capacitance behavior of laterally diffused MOS (LDMOS) transistors. It is shown that the modulation of channel/drift junction potential with V G, V D, and V S is primarily responsible for the capacitance peaks observed at different bias conditions. The V GS at which …

8.1 Capacitors and Capacitance

Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of Q or V.If the charge changes, the potential changes correspondingly so …

capacitor

The inner core signal is applied to a unity gain amplifier which projects back the same voltage onto the 1st (inner screen). This means that the inner core "sees" a capacitance that is vastly reduced. The outer screen is used as ground and of course the inner screen "sees" all the ground capacitance. I''ve used this on a capacitance probe too.

Cable shielding (best practices)

$begingroup$ @TimWilliams Capacitance is a non-sequitur how? The standard defines the maximum load capacitance (2.5 nF max) which includes the cable capacitance as well so why/how could the cable-shield or wire-shield capacitance be unrelated? As for shielding on one sides or both side, it depends on the application.

capacitor

Regards the LM35''s ability to drive into capacitors (coax cable or normal capacitors), there is a range of capacitance where the device will become unstable so you can either feed the output into a cable via a series resistor or shunt the output with a much larger capacitor in series with a resistor. In fact most op-amps exhibit this behaviour.

Ceramic Capacitor FAQ and Application Guide

Many instruments can be used to measure the electrical properties of capacitors. When measuring capacitance, these instruments apply a known AC voltage and frequency across the capacitor (device-under-test [DUT]) to measure the corresponding impedance. The capacitance is then extracted from the impedance measurement.

Capacitive Sensing: Ins and Outs of Active Shielding (Rev. A)

The sensing angle without a shield picks up any stray interference within the field-line vicinity. The sensing angle with a shield is dependent on how large the shield is compared to the sensor and how close the shield is to the sensor. Figure 2 illustrates how the sensor is focused by the use of a shield. An

Electric Fields and Capacitance | Capacitors | Electronics Textbook

When a capacitor is faced with a decreasing voltage, it acts as a source: supplying current as it releases stored energy (current going out the positive side and in the negative side, like a battery). The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance.
