2 micro farad. Their voltage capacity is maximum up to 100V. Now a days, polyester plastic film is used on the tissue paper in the paper capacitors. Due to the use of this film, its dielectric constant raises as a result it does not damages on the high voltage. Ceramic capacitors are generally of two types i. e.

There is very low frequency loss in it, because of these silient features it is used as dielectric material in the capacitors. These type of capacitors are known as mica capacitor. Since winding of mica is not possible therefore mica capacitor are always flat in shape. These capacitors are used where more accuracy and high dielectric constant is needed. Mica capacitors are of various types.

And, as was mentioned earlier, the voltage state of the cell for Static RAM is what determines the binary number the cell is said to hold. Carns, Zheng, and Wang, 1999Dynamic RAM uses capacitors in its binary interpretation. In understanding the method used for DRAM, we must remember that capacitors can be charged or discharged. Capacitors allow charge to build up on their conducting surfaces as current flows to them. Eventually, the capacitor reaches its limit, and the current stops, but the capacitor holds that charge in it.

While SRAM is said to be static, both SRAM and DRAM are volatile memories because they need a constant DC power source to maintain their states. If the power source is disconnected, the charges leave and the potentials drop to zero, erasing the information stored in all the cells. This is why the hard drive serves its special function of holding information even when the power is gone.

Tyson and Coustan, 2000 As we can see, DRAM uses less components in its process, but at the same time, the constant refreshing does require extra work. Both SRAM and DRAM have their pros and cons. Column and row decoders are the components involved in accessing specific cells. This is obviously needed when you consider the size of each memory chip and importance of being able to select only specific cells out of millions. The decoders work by highlighting each cell and making them available.

Ionic liquids are considered as great electrolytes for electrochemical energy. The liquids used in super capacitors include pyrrolidinium, imidazolium and asymmetric aliphatic quaternary ammonium salts of anions such as trifluoromethanesulfonate (Tf), tetrafluoroborate (BF4), hexafluoro‐phosphate (PF6), bis(trifluoromethanesulfonyl)imide (TFSI) and bis(fluorosulfonyl)imide (FSI). In addition to this, they are also utilized in lithium ion batteries. These batteries consist of organic solvents with a dissolved lithium salt such as lithium hexafluorophosphate.

The voltage oscillator Circuit Functions Inc. components are almost an inevitable part of all digital communication equipments. Wireless subscriber communication units such as the GSM use voltage oscillator circuits for generating radio frequency signals. A high frequency VCO is used in applications like processor clock distribution andteristic gain, which often is expressed as a ratio of the VCO output frequency to the VCO input voltage. The control voltage input typically may be tuned so that the VCO produces a desired, operational frequency output. The input control voltage is then adjusted up or down to control the frequency of the periodic output signal. A voltage controlled oscillator is capable of changing an oscillating frequency in response to a change in control voltages. A VCO typically employs one or more variable capacitors commonly called as varactors to allow for adjustment of the frequency of oscillation for the VCO.

Ionic liquids are thermally stable salts and possess strong properties at room temperature, which is why they are preferred as electrolytes for super capacitors. With unique physicochemical properties such as, high thermal stability, electrochemical stability and negligible vapor pressure, ionic liquids are suitable for electrochemical capacitors. On the other hand, due to their characteristic of high viscosity, the process of wetting of highly porous carbon is complicated. However, this issue is easily resolved by operating the capacitor at a higher temperature.
