This paper presents a dual-mode voltage-controlled oscillator (DMVCO) and a DMVCO-
based wideband frequency synthesizer for software-defined radio applications. The DMVCO …

This paper presents a dual-mode multiband transceiver with DigRF interface implemented in
a 0.13-μm CMOS technology. Based on direct conversion architecture, blocks in the …

A wideband digital RF receiver front-end employing a discrete-time (DT) filter is presented
for application to m-WiMAX (WiBro). By employing a sampling mixer and a DT filter, the …

Professional embedded electronic applications are found in military, security, or high
reliability systems like in avionics and aerospace. They have to meet specific requirements …

A low power broad band CMOS LNA for software-defined radio (SDR) applications is
presented. The LNA is based on the common source cascade amplifier with active feedback …

This paper presents two CMOS power amplifiers which realize frequency band selection.
Each PA consists of two stages and uses a transformer to obtain large output power with …

Advances in high-speed DAC implemented in deeply scaled-CMOS processes open up the
possibility of direct IF and RF waveform synthesis in a next-generation digitized transmitter …

This dissertation focuses on the design of wideband SAW-less receivers for softwaredefined
radios. The entire body of work is based on a single RF front-end architecture type: a …
