Abstract-To realize a Software Defined Radio covering the mainstream 0.5-6 GHz wireless communication bands, new SAW-less radio receiver architectures are being explored which realize selectivity in a more flexible and programmable fashion. N-path filters and mixer-first receivers can offer high-linearity high-Q RF-filtering around a center frequency defined by a digital clock, which offers the desired flexible programmability. This paper reviews recent research on N-path filters and mixerfirst receivers, identifies advances in performance analysis, circuit performance and applications.

“…consumption. As blockers are now amplified in the LNA despite of the N-path filtering, a high supply voltage may be desired in the LNA to allow for enough voltage swing without clipping [53]. Another motivation for this LNA-first architecture followed by N-path filtering is lower noise figure [57].…”

“…However, the frequency limitations above 3GHz coupled with the lack of tunability has led to the push for SAW-less receivers in recent implementations. Current methods of bandpass filtering make use of frequency dependant loads at the output of the first gain stage of the LNA [13]. More recent implementations have investigated additional blocker cancellation techniques at the baseband level with the use of frequency translational filtering.…”

“…More recent implementations have investigated additional blocker cancellation techniques at the baseband level with the use of frequency translational filtering. An advantage of this approach comes from the blocker signal being out of phase relative to the main signal, which allows further cancellation of the blocker at the baseband [13]. An implementation of this filtering technique in a feed-forward architecture has also been demonstrated [14].…”

Abstract-This invited paper considers a key next step in the design of radio architectures aimed at supporting low energy consumption in 5G heterogeneous radio access networks. Stateof-the-art mobile radios usually require one RF transceiver per standard, each working separately at any given time. Software defined radios, while spanning a wide range of standards and frequency bands, also work separately at any specific time. In 5G radio access networks, where continuous, multiband connectivity is envisaged, this conventional radio architecture results in high network power consumption. In this paper, we propose the novel concept of a concurrent multiband frequency-agile radio (CM-FARAD) architecture, which simultaneously supports multiple standards and frequency bands using a single, tunable transceiver. We discuss the subsystem radio design approaches for enabling the CM-FARAD architecture, including antennas, power amplifiers, low noise amplifiers and analogue to digital converters. A working prototype of a dual-band CM-FARAD testbed is also presented together with measured salient performance characteristics.

“…But manufacturers of analog devices are hard to keep up to wireless bands and services' development, where new service emerges every six months [1]. As first proposed by Mitola [2] in 1992, software-defined radio (SDR) has been developed for more than 20 years [4,5]. In this paper, part of the a zero-IF SDR receiver's baseband filters is reported.…”

Abstract. This paper reports an active RC trans-impedance low pass filter (TI-LPF) with variable gain and bandwidth that can be used in 200MHz to 6GHz zero-IF software-defined radio (SDR) receivers. This paper not only incorporates a single pole Butterworth TI-LPF, but also includes voltage detector for auto-gain control (AGC) systems. Influence of finite gain amplifier and the architecture of this zero-IF SDR receiver, which uses a 65-nm CMOS process, are introduced in this paper as well. Using 65nm CMOS process, this TI-LPF exhibits 64x bandwidth tunability (1MHz to 64MHz), 3 stages of trans-impedance gain of 71.2dBΩ, 67.6dBΩ and 65.1dBΩ, a static power dissipation less than 6.002mW, and a total summarized noise less than 5.969 x 10 -15 V 2 .
