Abstract; A compact reconfigurable CMOS low-noise amplifier (LNA) is presented for applications in DCS1800, UMTS, WLAN-b/g and Bluetooth standards. The proposed LNA features first a current reuse shunt-feedback amplifier for wideband input matching, low-noise figure and small area. Secondly, a cascode amplifier with a tunable active LC resonator is added for high gain and continuous […]

Abstract; Small signal RF modeling of FinFETs is strongly dependent on the methodology used to extract transistor intrinsic and extrinsic parameters. In this article, an original extraction method is proposed for determining all FinFET extrinsic series elements values from S‐parameters measurements at zero bias condition. The extracted technique is demonstrated through successful comparison between simulated […]

Abstract; In this letter, a new design method of ultra wideband bandpass filter (UWB BPF) is proposed. Based on a symmetrical structure of a simple uniform line loaded by a stepped-impedance open stub (SIS) connected at its center, the proposed design method employs simultaneously the optimization of a defined objective function in the range of […]

Abstract; A new approach is proposed to act as an efficient design technique for the implementation of ultra-wideband (UWB) bandpass filters in integrated passive device technology. The proposed design is based on two major original contributions. First, the use of hourglass filter theory which, to the best of authors knowledge, has not been applied yet […]

Abstract; In this letter, a new compact microstrip ultra‐wideband (UWB) bandpass filter (BPF) is proposed. Using a new electrical model leading to a simple structure based on radial stub resonator (RSR), its originality resides in its noteworthy simple design approach where the filter response can be accurately adjusted by tuning three parameters only. The fabricated […]

Abstract; This work provides a new co-design methodology of ultrawide band (UWB) low-noise amplifier (LNA) with high out of band interference cancellation. The solution consists to cascade a selective microstrip UWB bandpass filter (BPF) with the proposed 0.18 μm complementary metal-oxide-semiconductor-based LNA. Indeed, the usefulness of this co-design technique is to address the interference mitigation […]

Abstract; This paper focuses on the comparison of the RF performances of various advanced trap-rich (TR) siliconon-insulator (SOI) and porous silicon (PSi) substrates. The PSi substrates are produced by electroporisification starting either from cheap standard resistivity (10 Q·cm) silicon (PSi-S) or from the most widespread highly doped milliohm-centimeter Si wafers (PSi-M). Through small-signal RF measurements, […]
