As the field of communications networks continues to evolve, the challenging area of
wireless sensor networks is rapidly coming of age. Recent advances have made it possible …

Nowadays, a lot of effort is spent on developing inexpensive orthogonal frequency-division
multiplexing (OFDM) receivers. Especially, zero intermediate frequency (zero-IF) receivers …

Realizing multistandard transceivers with maximum hardware reuse amongst the given
standards is of great importance to minimize the manufacturing cost of emerging …

In this paper, a" composite" source-follower is presented. Using a positive-feedback, the
structure synthesizes complex poles with a single branch. This allows to realize a single …

A single-chip dual-band tri-mode CMOS transceiver that implements the RF and analog front-
end for an IEEE 802.11 a/b/g wireless LAN is described. The chip is implemented in a 0.25 …

Zero-IF receivers are gaining interest because they enable low-cost WLAN OFDM terminals.
However, zero-IF receivers introduce IQ imbalance which may have a huge impact on …

Sensor networks continue to grow in importance for modern communication networks. The
fruit of recent efforts aimed at miniaturization and highly advanced functionality, smart dust …

The drive for cost reduction has led to the use of CMOS technology in the implementation of
highly integrated radios. This paper presents a single-chip 5-GHz fully integrated direct …

A digital technique is adopted to calibrate the current mismatch of the charge pump (CP) in
phase-locked systems. In this digital calibration technique, there is no extra replica CP …

A fully integrated CMOS direct-conversion 5-GHz transceiver with automatic frequency
control is implemented in a 0.18-μm digital CMOS process and housed in an LPCC-48 …
