This paper presents the design and implementation of a novel pulse width modulation control class D amplifiers chip. With high-performance, low-voltage, low-power and small area, these circuits are employed in portable electronic systems, such as the low-power circuits, wireless communication and high-frequency circuit systems. This class D chip followed the chip implementation center advanced design flow, and then was fabricated using Taiwan Semiconductor Manufacture Company 0.35-μm 2P4M mixed-signal CMOS process. The chip supply voltage is 3.3 V which can operate at a maximum frequency of 100 MHz. The total power consumption is 2.8307 mW, and the chip area size is 1.1497×1.1497 mm2. Finally, the class D chip was tested and the experimental results are discussed. From the excellent performance of the chip verified that it can be applied to audio amplifiers, low-power circuits, etc.

Power Circuits

Low power circuits functioning in sub threshold were proposed in earlier seventies. Recently, growing with the need of low power consumption, the low power circuits have became more attractive. However, the act of sub threshold design logics has become sensitive to the supply voltage & process variations like temperature and so on. In sub threshold region of operations the supply voltage (Vgs) is less than the threshold (Vth).This leads to less power dissipation in over all circuit, but drastically increment in propagation delay. The major intention of the paper is to offer new low power & less delay digital circuits. SRAM is the major power drawing element and dissipation is about 40% in total power. The primary objective is to design of sub threshold SRAM design, Functionality and performance is estimated from the power and delay.The second objective is to offer novel Source coupled logic based SRAM (ST-SC SRA) M & Operating these design under sub threshold operating region. Performance is analyzed through power and delay. Finally comparing the traditional sub threshold SRAM with source coupled based SRAM in power and delay on par with the performance. Discussing some of the applications, where there is a requirement of less power and delay.

This paper proposes a realistic model of magnetizing branches for transient calculation of electric power circuits. The model represents the nonlinear relationship between flux linkage and exciting current of magnetizing branches with a major loop and a family of minor loop trajectories, which has the capability of simulating the multi-valued hysteresis behavior. By applying the proposed model to transient calculation, an efficient algorithm is developed for obtaining the transient responses in electric power circuits. In the algorithm, the electric power circuit is divided into the magnetizing branches and the remaining linear part. The nonlinear differential equations are set up for the magnetizing branches and solved by the semi-explicit Runge–Kutta method. The transient calculation for the remaining linear part is performed on the basis of the solution to the magnetizing branches. Then, a laboratory measurement is made with a reduced-scale experimental arrangement. The measured results are compared with the calculated ones and a reasonable agreement is shown between them.
