This letter presents a compact CMOS based variable gain amplifier with 60 dB gain control
range and a feedback reconfigurable dc offset cancellation. The design is a four-stage fully …

A low-power interference-tolerance wideband receiver with post-LNA active N-path filter for
RF channel selection is proposed for 802.1 af/ah long-range Wi-Fi standards. By leveraging …

In radio frequency identification (RFID) systems, performance degradation of phase locked
loops (PLLs) mainly occurs due to high phase noise of voltage‐controlled oscillators …

This work presents a configurable time-interleaved pipeline architecture as an efficient
solution for the ADC design in high data rate multi-standard radios. The ADC is implemented …

A new approach providing the active-RC integrator with programmable time constant is
proposed. An inherently linear current division network (CDN) preserving the high linearity …

This paper proposes a variable gain amplifier (VGA) with reconfigurable DC-offset
cancellation (DCOC) for multi-standard applications. In this design, a cell-based design …

Ultrawideband (UWB) communication based on the impulse radio paradigm is becoming
increasingly popular. According to the IEEE 802.15 WPAN low rate alternative PHY Task …

In this study, a multiphase fractional phase‐locked loop (PLL) is presented with methods to
reduce spurs. General causes of spurs are non‐idealities of the phase‐frequency detector …

In this paper, we present a complete multi-standard receiver based on a variable-gain LNA
and an RF subsampled Sigma-Delta ADC. The receiver includes an RF digital down …

Spurs are generated at the output of conventional PLLs due to nonidealities of the phase-
frequency detector and charge pump, and variation in the modulus of the frequency divider …
