“…The development of mobile devices and the need for high-speed communication have resulted in considerable research on receivers operating in the mm-wave frequency bands [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In [2][3][4], the beamforming receivers were implemented by combining four channels [2,3] and eight channels [4], respectively.…”

This paper presents a Q-band image-rejection receiver using a 65 nm CMOS technology. For a high image-rejection ratio (IMRR), the Q-band receiver employs the Hartley architecture which consists of a Q-band low-noise amplifier, two down-conversion mixers, a 90° hybrid coupler, and two IF baluns. In addition, a Q-band fundamental voltage-controlled oscillator (VCO) and a frequency divider chain divided by 256 are integrated into the receiver for LO. A charge injection technique is employed in the mixers to reduce the DC power while maintaining a high conversion gain and linearity. The VCO adopts a cross-coupled topology to secure stable oscillation with high output power in the Q-band. The frequency divider chain is composed of an injection-locked frequency divider (ILFD) and a multi-stage current-mode logic (CML) divider to achieve a high division ratio of 256, which facilitates the LO signal locking to an external phase-locked loop. An inductive peaking is employed in the ILFD to widen the locking range. The Q-band image-rejection receiver exhibits a peak conversion gain of 16.4 dB at 43 GHz. The IMRR is no less than 35.6 dBc at the IF frequencies from 1.5 to 5 GHz.

“…A wireless receiver is a key component of the satellite communication systems. Many Ka-band receivers have been reported in literatures using SiGe BiCMOS, GaN, and CMOS technologies [13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Yet these receivers are only for the communication purpose, not supporting a radiometric function capable of dynamically measuring the atmospheric conditions.…”

A highly-integrated reconfigurable Ka-band receiver in a 90-nm CMOS technology is proposed for the applications of satellite wireless communications, remote sensing of atmospheric conditions, and detection of space debris. The proposed receiver can be reconfigured to support active-receiver and passivereceiver modes. At the active-detection mode, it works as a direct-conversion coherent receiver for highspeed and global-coverage satellite communications. Measured conversion gain of 45.2 dB, noise figure of 7.6 dB, and output 1-dB compression point of -6.8 dBm can be acquired at 35 GHz while only consuming 54.4 mW from a 1.2-V supply. As switched to the passive-detection mode, it can potentially operate as a noncoherent radiometer to sense atmospheric conditions which are employed to dynamically compensate the atmospheric attenuation to mitigate the fading effects. This enables the satellite communication systems to establish reliable links. Moreover, the proposed passive receiver can be utilized to detect the space debris. Collisions can be avoided and hence satellite lifetime can be enhanced. Experimental results show that the proposed receiver at the passive-detection mode exhibits voltage responsivity of 1.2 GV/W and noise equivalent power (NEP) of 2.1 aW/Hz 0.5 at 35 GHz. The power dissipation is only 49.6 mW from a supply voltage of 1.2 V. To the best of the authors' knowledge, the proposed receiver owns the highest responsivity and the lowest NEP at Ka-band reported thus far. It is also the first receiver capable of being reconfigured to support active-detection and passive-detection modes according to different application scenarios.INDEX TERMS Reconfigurable, Ka-band, CMOS, active receiver, passive receiver, satellite communications, radiometer, effect of fading, space debris.

This study presents an ultra-wideband receiver front-end, designed for a reconfigurable frequency modulated continuous wave radar in a 130 nm SiGe BiCMOS technology. A variety of innovative circuit components and design techniques were employed to achieve the ultra-wide bandwidth, low noise figure (NF), good linearity, and circuit ruggedness to high input power levels. The designed front-end is capable of achieving 1.5–40 GHz bandwidth, 30 dB conversion gain, a double sideband NF of 6–10.7 dB, input return loss better than 7.5 dB and an input referred 1 dB compression point of −23 dBm. The front-end withstands continuous wave power levels of at least 25 and 20 dBm at low band and high band inputs respectively. At 3 V supply voltage, the DC power consumption amounts to 302 mW when the low band is active and 352 mW for the high band case, whereas the total IC size is $3.08\, {\rm nm{^2}}$ .
