This paper presents the design, fabrication and performance of a three-stage 155GHz monolithic low noise amplifier (LNA) using 0.1 -pm pseudomorphic (PM) InAIAs/InGaAs/InP HEMT technology. This amplifier exhibits a measured small signal gain of 12 dB at 155 GHz, and more than 10 dB gain from 151 to 156 GHz. When this amplifier is biased for low noise figure, a noise figure of 5.1 dB with associ...

A 1.8V, 2.4 GHz CMOS low noise amplifier (LNA) is proposed to be used in front end receiver of Wireless LAN (WLAN) and Industrial Scientific and Medicine (ISM) band. The circuit is simulated in tsmc 180nm V 3.2. The optimization for the width of the CMOS is done taking into consideration parameters viz. noise figure (NF), Power consumption, gain, stability and linearity. The matching of input c...

This article presents a direct down-conversion mixer for ultra-wideband systems on 0.18 m RF CMOS process. The proposed mixer uses a current bleeding technique and an internal resonant inductor to improve the conversion gain and noise figure of the conventional Gilbert-cell mixer. Effects of each technique are compared on mixer’s noise performance. Measured results show the conversion gain of 7...

This paper proposes a new method fo r noise parameter measurement of microwave devices. Instead of measuring the noise figure, the optimum source impedance r o p t is determined by measuring the noise powers corresponding to cold impedances, then the minimum noise figure Fmn ( 0 r minimum effective noise temperature T,,,) and noise conductance Gn are determined by connecting a calibrated hot no...

1 Noise is composed of undesirable signal components that arise from various sources in an electronic imaging system. The figure of merit that dictates the ultimate performance of a system is signal-to-noise ratio (SNR), which describes the quality of a measurement (see Figure 1). In CCD imagine, SNR refers to the relative magnitude of the signal compared to the uncertainty in that signal on a ...

A design methodology for wideband CMOS low noise amplifier (LNA) with source degeneration is presented. By allowing an arbitrary source degeneration and employing a general input matching network, the minimum noise figure of the proposed wideband CMOS LNA can be made independent of the transistor width by properly choosing the source degeneration reactance. This result shows that the proposed t...

A gain boosting method without noise-figure degradation by optimizing interstage matching in a cascode low-noise amplifier (LNA) with emitter-degeneration inductor is demonstrated at 5.2 GHz using 2m GaInP/GaAs HBT technology. A low-pass LC matching network is inserted in the interstage of a conventional cascode LNA with emitter-degeneration-inductor to enhance the gain with the same current co...

In this paper, we investigate the noise and large-signal behavior of a feedback amplifier in multilayer thin-film MCMD technology. A small-signal equivalent model (including noise) of the active devive, a thin-film MHEMT, is identified. A large-signal state-space transistor model is built from timedomain data. These models are implemented in a circuit simulator and can accurately predict the no...
