Shunt Capacitance Compensation in Operational Amplifiers
In this article, we''ll discuss how shunt capacitance can be used to achieve frequency compensation in op-amps and we''ll also see why this is not the preferred technique. In a recent article on the frequency compensation of operational amplifiers, we discussed what the concept of frequency compensation is and how we can evaluate an …
Do you know what reactive power compensation is? If not, keep …
Before we get into the depth of describing the compensation applications and other details, let''s remind ourselves of the power flow basics. As you can see from Figure 1, the flow of power in an electric circuit is illustrated. The link has an impedance of R+jX, and we assume that V 1 >V 2 and that V 1 leads V 2..
The impact of input capacitance on op-amp stability
The new closed-loop bandwidth with a compensation capacitor is equal to the zero frequency created by C F and R2. If you need to maximize the overall bandwidth of the circuit, f z_cf can be greater than …

Figure 6. Phase compensation capacitor C F helps improve stability. Figure 7. Phase response with the phase-compensation capacitor, C F. A good design compromise is to target 45 degrees of phase margin at the intercept of the A VOL (jω) and 1/β(jω) curves.
What is Reactive Power Compensation? – Capacitor Connect
Methods of reactive power compensation In most cases, the compensation is capacitive. A system may use capacitors in parallel (shunt) to line, or it may be in series, incorporated in the transmission line circuit. Depending on application, the compensation may

What is capacitance compensation
Capacitance compensation is reactive power compensation or power factor compensation. The electrical equipment of the power system generates reactive power when in use, and it is usually inductive, which will reduce the efficiency of the power supply capacity, which can be improved by appropriately adding capacitance in the system.

Abstract—Frequency compensation of two-stage integrated- circuit operational amplifiers is normally accomplished with a capacitor around the second stage. This compensation …
Frequency compensation
Because operational amplifiers are so ubiquitous and are designed to be used with feedback, the following discussion will be limited to frequency compensation of these devices. It should be expected that the outputs of even the simplest operational amplifiers will have at least two poles. A consequence of this is that at some cr…
