“…LNA is used in the receiver side of the transceiver system to improve the receiver sensitivity level for better performances in the presence of interference by introducing high gain and better Noise Figure. Tunable RF components have drawn much research attention to realize a robust and highly reconfigurable RF transceiver for applications intended to software-defined and cognitive radio platforms [2]. For improving the robustness and performance of the receiver in the presence of interference, a variable gain amplifier has been utilized [3]. A reconfigurable LNA is realized by making input matching network tunable but it is not a concurrent dual-band system [4].…”

Concurrent dual-band reconfigurable low noise amplifier (LNA) for noninvasive detection of human vital signs has been reported in this paper. The reconfigurable output matching network used in this LNA (PHEMT ATF-36163) consists of two shunt stubs terminated by varactor diodes (SMV1232-079LF); while the matching network at input side of the LNA has been designed for fixed dual band operation. The measured characteristics of the fabricated prototype shows that the gain of the LNA varies from 3 dB to 12.2 dB in the frequency range of 2.3-2.5 GHz; while it varies from 9.5dB to 12.9 dB in the frequency range of 4.2-4.6 GHz for a variation in varactor voltages from O-IOV. The simulated value of the Noise Figure of the amplifier is -0.5 dB and 2.5 dB at the centre frequency of the corresponding frequency bands.

“…Recently, several successful implementations of fully integrated GNSS RXs, including GPS/GLONASS/ Galileo/Compass systems have been reported in [10]- [12]. Two independent channels are utilized in [10] and [11] to receive dual-band GNSS signals, which result in that the bandwidth of each IF channel (IFC) must be adaptive for different chip rate of GNSS signals. This will significantly increase the design complexity of the RX and consume more chip area.…”

“…This will significantly increase the design complexity of the RX and consume more chip area. Moreover, two identical chips must be used when some dual-band GNSS signals are utilized to provide LBS in [10] and [11], which will significantly increase design cost and printed circuit board (PCB) area. Only one receiving channel utilizing low-pass filter (LPF) is incorporated in [12] to receive dual-band GNSS signals simultaneously, which decreases complexity, die area, and mostly current consumption comparing with dual-channel ones in [10] and [11].…”

This paper presents a fully integrated reconfigurable all-band RF transceiver for GPS/GLONASS/ Galileo/Beidou in 55-nm CMOS. The transceiver incorporates three low-IF receivers (RXs) and one direct up-conversion BPSK transmitter (TX), which can be configured to receive any two global navigation satellite system (GNSS) signals or switched to process the Chinese Beidou(I) signals. A switching module is integrated to provide the connectivity between different RF front-end and IF channel (IFC), which will effectively simplify the design complexity of the IFC and save power consumption, while the GNSS signals are received. A flexible frequency plan with two frequency synthesizers is utilized to satisfy different local oscillator requirements of the transceiver. An optimized automatic frequency calibration scheme using an error compensation logic enables fast and high-precision calibration process for optimum phase-locked loop operation. Several digitally assisted calibration modules are integrated to ensure that the chip performance only shows a weak process, voltage and temperature (PVT) dependence. While drawing about 21.5-30.2 mA per RX channel from a 1.2-V supply, the RXs achieve an image rejection ratio more than 49 dB after I/Q mismatch calibration, an automatic gain control range of 88 dB, and an input-referred 1 dB compression point of better than −25 dBm with a minimum noise figure of about 2 dB. The output power of the TX is about 5 dBm with about 6% error vector magnitude (EVM) and 30-mA current from a 1.2-V supply. The whole transceiver consumes a die area of 2.8 × 3 mm 2 .
