CLASS-D AMPLIFIERS
Abstract
Class D amplifiers present us with a revolutionary solution, which would help us eliminate loss and distortions caused due to conversion of digital signals to analog while amplifying signals before transmitting it to speakers. This inchoate piece of knowledge could prove to detrimental in improving and redefining essence of sound and take it to a different realm.

This type of amplifiers do not require the use of D-A conversion and hence reduce the costs incurred for dev ....etc

Digital technology continues its march from media like CDs and DVDs toward your audio speakers. Today, amplifiers based on digital principles are already having a profound effect on equipment efficiency and size. They are also beginning to set the standard for sound quality.

An old idea, the Class D amplifier has taken on new life as equipment manufacturers and consumers redefine the musical experience to be as likely to occur in a car, on a personal stereo, or on an airplane as in a living room. For most consumers today, portability and st ....etc

Common mode rejection ratio (CMRR) is important performance parameter of any difference amplifier. It is the ratio of the differential gain to the common-mode gain, generally expressed in dB. It signifies the ability of an opamp to reject common mode signal, the signal which appears simultaneously at both its input terminals. The CMRR is of great importance when it comes to noise rejection. For applications involving high CMRR, instrumentation amplifiers consisting of three opamps are generally used. It has a major disadvantage that the value o ....etc
