“…In this receiver implementation, the LO phase noise is traded for low power consumption. On the other hand, the achieved noise figure of 9 dB for a −20-dBm blocker located 40-MHz offset is competitive with the reported performance of other state-of-the-art low-power RXs-a 13.7-dB NF for a −20-dBm blocker at a 50-MHz offset [33] and an 18-dB NF for a −10-dBm blocker at a 400-MHz offset [17]. In addition, the targeted IoT standards, such as Bluetooth and NB-IoT, expect their receivers to tolerate −27-dBm/−30-dBm blocker at 80-/60-MHz offset.…”

In this article, we present a passive mixer-first receiver front end providing a low-power integrated solution for high interference robustness in radios targeting Internetof-Things (IoT) applications. The receiver front end employs a novel N-path filter/mixer, a linear baseband amplifier, and a step-up transformer to realize sub-6-dB NF and >20-dBm OB-IIP3 concurrently. The proposed N-path filter/mixer exploits an implicit capacitive stacking principle to achieve passive voltage gain of 3 during down-conversion and high out-ofband linearity simultaneously while using at least 2× less total capacitance for the same RF bandwidth compared to a conventional switch-capacitor N-path filter. Fabricated in 22-nm complementary metal-oxide-semiconductor (CMOS) fully depleted silicon on insulator (FDSOI), the receiver prototype-including a 2:6 transformer-occupies only 0.2 mm 2 of active area. Operating in the frequency range of 1.8-2.8 GHz, the front end provides a 45-47-dB conversion gain and a baseband bandwidth of 2 MHz. Due to passive voltage gain in the filter/mixer and transformer, the implemented front end consumes only 1.7-2.5 mW of power to achieve <6-dB NF, ∼24/60/1 dBm out-of-band IIP3/IIP2/B1dB, respectively.

“…While this implementation is able to generate accurate quadrature signals, the dividers operating at the double of the carrier frequency leads to high power consumption when a low cost technology (e.g., 130 nm and above) is adopted. Such strategy becomes competitive only for shorter channel length as shown in [12], [13]. Quadrature LO signals can also be generated through poly-phase RC filters, which rely heavily on the matching of the devices to provide adequate quadrature accuracy.…”

In this paper, a receiver front-end tailored to Bluetooth Low Energy applications is presented. In the proposed solution, the LNA, mixers, VCO, quadrature scheme and the first stage of the analog base-band share the same bias current under a 0.8 V voltage supply leading to a sub-mW power consumption. A channel selection filter, implemented through a current re-use gm-C topology, completes the design. The presented prototype, realized in 130 nm CMOS technology, occupies an active area of 0.25 mm while consuming only 0.6 mW. With a NF of 15.8 dB, an IIP3 of 17 dBm at the maximum gain and an image rejection above 30 dB the receiver front-end meets BLE noise figure, image rejection, phase noise and linearity requirements.

“…With the growing demand for the Internet of Things (IoT), receivers that comply with the 2.4 GHz Bluetooth low energy(BLE) standard are one of the most attractive candidates for wireless sensor applications with low power consumption, short-range, high data rate for wearable devices such as smart bracelets and smartphones that require low-power wireless data links [1,2,3,4,5,6,7,8,9,10,11,12]. Low-power design is an important requirement for BLE systems to extend battery life and long-term stable operation [6,13,14,15].…”
