A new 1.575 GHz active balun with a classic double-balanced Gilbert mixer for global navigation satellite systems is proposed herein. A simple, low-noise amplifier architecture is used with a center-tapped inductor to generate a differential signal equal in amplitude and shifted in phase by 180°. The main advantage of the proposed circuit is that the phase shift between the outputs is always equal to 180°, with an accuracy of ±5°, and the gain difference between the balun outputs does not change by more than 1.5 dB. This phase shift and gain difference between the outputs are also preserved for all process corners, as well as temperature and voltage supply variations. In the balun design, a band calibration system based on a switchable capacitor bank is proposed. The balun and mixer were designed with a 110 nm CMOS process, consuming only a 2.24 mA current from a 1.5 V supply. The measured noise figure and conversion gain of the balun and mixer were, respectively, NF = 7.7 dB and GC = 25.8 dB in the band of interest.

A low-power, wideband signaling receiver for data transmission through a human body was presented in this paper. The receiver utilized a novel implementation of energy-efficient wideband impulse communication that uses the human body as the transmission medium, provides low power consumption, high reception sensitivity. The receiver consists of a low-noise amplifier, active balun, variable gain amplifier (VGA) Gm-C filter, comparator, and FSK demodulator. It was designed with 0.18um CMOS process in an active area of 1.54mm0.414mm. Post-simulation showed that the receiver has a gain range of-2dB~40dB. The receiver consumes 4mW at 1.8V supply and achieves transmission bit energy of 0.8nJ/bit.

The paper presents a design and simulation study of three active balun circuits implemented in a standard 90nm Complementary Metal-Oxide Semiconductor (CMOS) process namely: (1) common-source/drain active balun; (2) common-gate with common-source active balun; and (3) differential active balun.  The active balun designs are intended for Worldwide Interoperability for Microwave Access (WiMAX) applications operating at frequency 5.8GHz and with supply voltage of 1V.  Measurements are taken for parameters such as gain difference, phase difference, and noise figure.  All designs achieved gain difference of less than 0.23dB, phase difference of 180° ± 7.1°, and noise figure of 7.2–9.85dB, which are comparable to previous designs and researches.  Low power consumption attained at the most 4.45mW.

This study presents a CMOS distributed amplifier (DA) with pseudo differential amplifying that achieves DC-40[Formula: see text]GHz bandwidth (BW) in 0.18-[Formula: see text]m RF CMOS process. The DA with three-stage amplifying cells was proposed to improve the DA performance. The inter-stage was composed of pseudo differential amplifying for bandwidth extension. By incorporating the pseudo differential amplifier configuration and capacitor-less circuit in the stages, the DA provides average gain and high bandwidth. The simulation results showed that the DA has a S[Formula: see text] of 6.4[Formula: see text]dB, 3-dB BW from DC up to 40[Formula: see text]GHz. It also has a minimum noise figure (NF) of 4.27[Formula: see text]dB, one dB compression point (P[Formula: see text] of [Formula: see text]3.5[Formula: see text]dBm, a high reverse isolation S[Formula: see text] of less than [Formula: see text]15[Formula: see text]dB, an input return loss S[Formula: see text] and output return loss S[Formula: see text] of less than [Formula: see text]16 and [Formula: see text]12[Formula: see text]dB, respectively. It consumes 115[Formula: see text]mW and occupies a total active area of 0.27[Formula: see text]mm2.

The design of distributed amplifiers (DAs) is one of the challenging aspects in emerging ultra high bit rate optical communication systems. This is especially important when implementation in submicron silicon complementary metal oxide semiconductor (CMOS) process is considered. This work presents a novel design scheme for DAs suitable for frontend amplification in 40 and 100 Gb/s optical receivers. The goal is to achieve high flat gain and low noise figure (NF) over the ultra wideband operating bandwidth (BW). The design scheme combines shifted second tire (SST) matrix configuration with cascode amplification cell configuration and uses m-derived technique. Performance investigation of the proposed DA architecture is carried out and the results are compared with that of other DA architectures reported in the literature. The investigation covers the gain and NF spectra when the DAs are implemented in 180, 130, 90, 65 and 45 CMOS standards.The simulation results reveal that the proposed DA architecture offers the highest gain with highest degree of flatness and low NF when compared with other DA configurations. Gain-BW products of 42772 and 21137 GHz are achieved when the amplifier is designed for 40 and 100 Gb/s operation, respectively, using 45 nm CMOS standard. Thesimulation is performed using AWR Microwave Office (version 10).
