In the recent past, there has been an evolution in wireless communications toward
multifunctions and multistandard mobile terminals. Reducing the number of external …

All-CMOS radio transceivers and systems-on-a-chip are rapidly making inroads on a
wireless market that for years was dominated by bipolar and BiCMOS solutions. It is not a …

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

An active filtering technique to remove the out-of-band blockers in wireless receivers is
presented. The circuit employs a feed-forward filtering path to produce an arbitrarily narrow …

Injection-locked LC dividers for low-power quadrature generation are discussed in this
paper. Modeling the circuits as regenerative frequency dividers leads to very simple …

This paper describes a sign-sign least-mean squares (LMS) technique to calibrate gain and
phase errors in the signal path of a Weaver image-reject receiver. The calibration occurs at …

Modern RF receivers and transmitters require quadrature oscillators with accurate
quadrature and low phase-noise. Existing literature is dedicated mainly to single oscillators …

We present the receiver in the first single-chip GSM/GPRS transceiver that incorporates full
integration of quad-band receiver, transmitter, memory, power management, dedicated ARM …

Wireless sensor network systems are now being applied by an international community for
critical applications in commerce, healthcare, and security. These systems have unique …

A fractional-N phase-locked loop (PLL) serves as a Gaussian minimum-shift keying (GMSK)
transmitter and a receive frequency synthesizer for GSM. The entire transmitter/synthesizer …
