This paper presents a wide-band fractional-N frequency synthesizer for multi-standard
cellular and short-range wireless communication receivers. The synthesizer covers the …

A 54-862-MHz single-chip CMOS transceiver with a single LC voltage-controlled oscillator
(VCO) fractional-N synthesizer is developed for TV-band white-space communications and …

Many and ever more mobile users wish to enjoy a variety of multimedia services, in very
diverse geographical environments. The growing number of communication options within …

This paper presents a 4th-order reconfigurable analog baseband filter for software-defined
radios. The design exploits an active-RC low pass filter (LPF) structure with digital assistant …

Analogue baseband filters are an important circuit for channel select and anti-aliasing in
wireless and mobile communication systems. For software and cognitive radio, they must be …

Wireless bands and services are proliferating across the world. Every six months
approximately, a new use for wireless appears, often leading to a new standard …

A wideband, low noise, and highly linear transmitter for multi-mode radio is presented.
Envelope injection scheme with a CMOS amplifier is developed to obtain sufficient linearity …

For measuring quad-band module system using WiBro network, frequency converter was
developed. The size of the fabricated frequency converter is $3.1 cm {\times} 3.1 cm {\times} …

This paper presents three CMOS power amplifiers (PA) which realize wide-tunable output
impedance matching. For realization of multi-standard and single-chip transceiver, the …

Abstract A Software-Defined Radio (SDR) should theoretically receive and transmit any
modulated frequency channel in the (un) licensed spectrum, targeting all modern …
