Class D amplifiers are not new, they have been in the industry since the 1960's but not often used in high fidelity applications. In the early sixties, Electro Magnetic Interference (EMI), in class D amplifiers, was a critical milestone in some application and linear counter- part took preference over class D. However in today's market, high efficiency for thermal management and battery life time, has favored class D, over the already existing linear solution.

520 $a Class D amplifiers are not new, they have been in the industry since the 1960's but not often used in high fidelity applications. In the early sixties, Electro Magnetic Interference (EMI), in class D amplifiers, was a critical milestone in some application and linear counter- part took preference over class D. However in today's market, high efficiency for thermal management and battery life time, has favored class D, over the already existing linear solution.
520 $a Clipping of the audio signal produces distortion, a product not desired in hifi applications. In the industry, several methods are used to rectify this known problem. In this thesis, two novel architectures were used to rectify the clipping that occurs in class D amplifiers. Method 1 "V_High V_Low method" completely eliminates clipping of the audio signal. Method 2 "Mid-Point method" a variation of method 1, which eliminates clipping within the desired audio input.
520 $a Both the architectures were driven from the concept phase to design phase through simulation. The methods were simulated using behavioral level leading to transistor level. The correlation between the behavioral level and transistor level is very close in functionality, proving that the concept and design was indeed a success.
