In this paper, a technique to extend the linearity and to improve the efficiency of power amplifiers (PAs) is analyzed. The method avoids complex topologies, often affecting the radio-frequency performance and increasing the power consumption, chip a
This work presents the design of two compact multi-standard low-noise amplifier (LNA) in a 28 nm low-power bulk CMOS process. The transistor parameters were optimized by the gm/ID method taking into account the parasitics and the behavior of highly s

We present a fully integrated auto-transformer-based power amplifier with totem-pole driver exhibiting a very high bandwidth. In order to simplify the design process a structural analysis and optimization method for the transformer are presented as w

This work investigates vector modulators with respect to their applicability in agile beamsteering frontends. The turnover time, i.e. the time necessary for an amplitude or phase change, of two vector modulators is characterized. Both circuits offer

A broadband radio frequency (RF) variable gain amplifier (VGA) enhanced with a gain control and automatic input impedance matching is presented in this work. Due to the control loop, the gain is linear-in-magnitude versus the control input. Additiona

A broadband variable gain amplifier (VGA) with low phase variation versus control range is presented in this work. The measured phase variation of less than 3.5° versus the high gain control range of 25dB make this VGA a suitable building block for

This paper demonstrates a 34 Gbit/s 4:1 multiplexer with 200 mW power dissipation in a 0.25-μm SiGe process. A multiphase clock architecture at half-rate clock is chosen to reduce the power dissipation. In addition, stability issues caused by the ca
