A fully CMOS gm block for low voltage, low power, and wide tuning range is presented in
this paper. The relative tuning range of 25 is achieved in this transconductor while only …

By sharing building blocks between different applications and standards, portable wireless
devices gain advantage over their predecessors: they use a smaller chip area, consume …

In this paper a new structure for the MLF (Multi Loop Feedback) Gm-C group of filters is
presented, granting the advantages of both current-mode and fully balanced topologies to …

A 4 th-order channel selection low-pass Gm-C filter for multi-mode wireless receivers is
presented. The filter is designed with a Chebyshev prototype and supports different wireless …

In this paper, we have presented a phase loop for controlling a chain of g mC all-pass filters.
It's called Delay Locked Loop for Analog Signal Processing, and it's used for signal's phase …

Abstract Current Passive Mixers represent the state of the art for the signal down-conversion
in wireless receivers. In such kind of structures, noise, distortion, and losses are strictly …

This chapter outlines the application of adaptivity to multi‐standard low‐power wireless
radio‐frequency (RF) circuits. It describes a multi‐mode receiver concept in the framework of …

Ultra-wideband phased array systems have attracted more and more interest in the modern
radio development. With the extensive growth of low cost silicon (Si) based Complementary …

Algumas aplicações na área de comunicação utilizam múltiplos comprimentos de banda, e,
portanto, necessitam de maior flexibilidade por parte do rádio de recepção. Se focarmos a …
