This article presents guidelines to design a dual-standard fully-integrated RF receiver front-end (RFFE). The designed front-end consists of two system selection integrated FBAR filters, a dual-standard low-noise amplifier (LNA), an active single-to-differential converter (SDC) and I/Q downconversion mixers. The active blocks use the 0.25-mm 60-GHz fT(More)
The authors present in this article a dual-standard dual-mode low-noise amplifier (LNA) for DCS1800/W-CDMA-FDD applications. In order to save die area compared to conventional parallel LNAs, an alternative circuit configuration have been used. It consists of sharing the most die consuming elements (inductances) in both operation standards, enabling a more(More)

This paper presents a dual-mode RF receiver front-end consisting of a LNA, an active single-ended-to-differential converter and a downconversion mixer. It uses a high performance 0.25-&#956;m 60-GHz <i>fr</i> SiGe:C BiCMOS7RF integration technology from STMicroelectronics. The proposed RF receiver front-end (RFFE) is targeted to GSM1800 (1805-1880MHz) and(More)
With the use GaAs pseudomorphic high electron-mobility transistor technology, the bandwidth performances of Cherry-Hooper driver amplifiers need to be improved. To fulfill these requirements, we propose an original driver circuit topology dedicated to 40-Gb/s optical communication systems. To flatten the transducer gain response of the circuit, passive(More)
