This article presents the design of a novel quadband LNA operating in the GSM 0.9GHz/GSM l.8GHz and ZigBee 0.9GHz/WLAN 2.4GHz communication standards. This pseudo-concurrent architecture uses a two bit mode switch for selecting between the frequency bands. An RF switch is implemented before the Low Noise Amplifier (LNA) module to improve the insertion loss(More)
Physical models and scaled prototypes of architecture play an important role in design. They enable architects and designers to investigate the formal, functional, and material attributes of the design. Understanding digital processes of realizing scaled prototypes is a significant problem confronting design practice. This paper reports on three approaches(More)
This paper features the design and detailed analysis of a fully concurrent dual-band Low Noise Amplifier (LNA) operating in the GSM 0.9GHz & BLUETOOTH 2.4GHz communication standards having an inter-stage matching inductor. An interstage inductor between the common source stage and the common gate stage is used to increase power gain. In this work, all(More)
