Ubiquitous computing, or pervasive computing, is an increasing popular technique for developing new human-computer interfaces and computer applications. Computers watch what happens in a physical space where people are and serve them with meaningful information. Here, most of the systems depend on visual interaction, while there are some other interaction(More)
This paper addresses the ESD reliability issues in RFICs, focusing on the technology impact on the device and design. We also present the basic RF ESD protection methods used in industry. Presents the general topology of a 5 GHz LNA, which is protected using several ESD protection methodologies, and describes the 90 nm CMOS process technology used for the(More)
Above-IC inductors enable low-power RF circuit design, and in addition efficiently protect the RF pins against electrostatic discharge (ESD) stress. This is demonstrated using above-IC inductors in the design of a fully integrated 5 GHz ESD-protected LNA and VCO in 90 nm CMOS. The LNA without ESD protection shows 1.4 dB NF, with 18 dB gain, drawing 4 mA(More)
ESD protection strategies utilized in RF circuit applications in CMOS and BiCMOS technologies are investigated and the results are presented in this paper. The conventional approach using diodes with power clamp is compared with novel approaches such as plug-and-play passive elements and full or partial circuit-ESD co-design. The trade-offs are discussed(More)
