In both digital and analog electronic circuits a capacitor is a fundamental element. It enables the filtering of signals and it provides a fundamental memory element. The capacitor is an element that stores energy in an electric field. The circuit symbol and associated electrical variables for the capacitor is shown on Figure 1. Figure 1.
One way of enhancing capacitor performance is by reducing internal inductance. Considerable inductance reduction is achieved by using correct materials and suitable construction techniques. The need to maintain high performance, miniaturise circuit, and control cost is the main driver towards new types of capacitors.
Capacitors are widely used in electronic circuits for storing and managing energy. Typical applications include filtering, decoupling, energy storage, and tuning. Some applications such as decoupling demand low impedance, high ripple current capability, and excellent surge performance.
Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F). The presence of time in the characteristic equation of the capacitor introduces new and exciting behavior of the circuits that contain them. Note that for DC (constant in time) dv signals ( = 0 ) the capacitor acts as an open circuit (i=0).
High performance capacitors with very low ESLs are increasingly replacing conventional ceramic, tantalum, and aluminum capacitors. Tantalum polymer capacitors and aluminum polymer capacitors are some of the new solutions for decoupling applications in high performance circuits.
Self inductance is one of the key parameters to consider when selecting a capacitor for high speed digital circuits. In theory, capacitors are commonly considered as ideal components. However, practical capacitors are non-ideal and contain parasitic elements – loses – that can significantly affect their performance.
