Linearised distributed amplifier with low linearisation loss

A fully-integrated linearized CMOS distributed amplifier based on Multi-Tanh principle for radio over fiber and ultra-wideband applications

“…One solution to this problem is broadband linearization. Distributed amplifier (DA) linearization techniques proposed by Parkinson [2] and Tsun Mok ( [3], [4]) were implemented at circuit-level involving discrete components limiting their bandwidth performance and as a result can not be used for ultra-wideband applications due to bandwidth limitations.…”

Self‐biased distributed amplifier: Linearity improvement and efficiency enhancement

“…However, these linearizers operate optimally only in a narrow bandwidth as the operations are generally frequency-dependent. Mok et al [5] have proposed a linearized distributed amplifier with the aid of a parallel diode, but the low average power efficiency still remains a problem. We have introduced a self-adaptive bias network [6], which mainly works on low frequency distortion components, unifies linearity improvement and efficiency enhancement for bipolar amplifiers.…”

“…In general, the conventional SPR sensor treats only the real part of the refractive index. Recently, an absorption-based SPR sensor has been studied for measuring the changes in not only the real but also the imaginary parts of the refractive index [2][3][4][5][6]. The behavior of absorption-based SPR responses has been discussed in [3].…”

Higher‐efficiency‐biasing technique for enhancing the performance of BJT‐distributed amplifiers

“…To support the above services using a single circuit, a wideband topology is needed. Because of the distributed amplifier's (DAs) [1][2][3][4] advantage of flat gain and no matching network required, DAs are commonly used in wideband amplification. However, most of the Field-effect transistor distributed amplifier's (FET DAs) operating frequency bands lies between DC to 10 GHz which is not cost effective when used in common consumer applications.…”
