In this paper, we analyze a distributed amplifier based on input/output attenuation compensation. The analysis is carried out for a HEMT transistor; and a constant-k section filter is used to calculate the amplifier’s characteristics such as attenuation factor, phase constant and gain. The proposed design approach enables us to examine the tradeoff among the variables, which include the type an...

Sense amplifiers are one of the very important peripheral components of CMOS memories. In a Hybrid Sense amplifier both current and voltage sensing techniques are used which makes it a better selection than a conventional current or voltage sense amplifiers. The hybrid sense amplifier works in three phases-Offset cancellation (200ps), Access phase (500ps) and Evaluation phase. The offset cancel...

A new symmetrical topology switching power amplifier is introduced for professional audio use. The amplifier is composed by a pair of semi soft switched half-bridges with independent feedback control. Whole overall layout looks very similar than an already bridge configured stereo amplifier with few exceptions. Although the complexity of the proposed topology is at least twice of the convention...

Stable picosecond soliton transmission is demonstrated numerically by use of concatenated gain-distributed nonlinear amplifying fiber loop mirrors (NALMs). We show that, as compared with previous soliton transmission schemes that use conventional NALMs or nonlinear optical loop mirror and amplifier combinations, the present scheme permits a significant increase of loop-mirror (amplifier) spacin...

t is reported that millions of people are suffering from some kind of hearing impairment [1]. The number is climbing due to the increasing portion of elderly people in the world's population. While hearing loss is usually caused by permanent mechanical damage to the ear, there is no medicine to reverse it, and surgery offers little help. Thus, electronic hearing aids or pros-thetics are, so far...
