Abstract A fully-integrated silicon-based 94-GHz direct-detection imaging receiver with on-chip Dicke switch and baseband circuitry is demonstrated. Fabricated in a 0.18-μm SiGe BiCMOS technology (f T/f MAX= 200 GHz), the receiver chip achieves a peak imager responsivity of 43 MV/W with a 3-dB bandwidth of 26 GHz. A balanced LNA topology with an embedded Dicke switch provides 30-dB gain and enables a temperature resolution of 0.3-0.4 K. The imager chip consumes 200 mW from a 1.8-V supply.

This paper presents an Ultra-Low-Power (ULP), high integration, and wide bandwidth low-IF radio frequency receiver for millimeter-wave (mm-wave) applications using 130 nm CMOS technology. The proposed radio receiver is composed of a low-noise driver stage implemented using a complementary current reuse common gate with an active shunt feedback configuration, and an in-phase/quadrature of phase (I/Q) demodulator. The driver stage is used to expand the input RF impedance matching with acceptable linearity and gain at an ultra-low DC power dissipation. Moreover, the transformer coupling between the trans-conductance and switching stages is used to separate the DC bias between those two stages, the transformer is a high coupling factor wideband width 5-ports transformer. The DC supplies of the proposed mm-wave radio frequency receiver are implemented using two energy-harvesting voltage doubler designs. The proposed mm-wave radio receiver dissipates 0.475 mW from a 1.1 V DC supply and it...

This paper presents millimeter-wave CMOS building blocks for a high date rate wireless transceiver. The results include measured data for a 40-50 GHz broad-band low noise amplifier, a 40 GHz tuned power amplifier, and an 18 GHz voltage controlled oscillator. Also, simulation results for a 22 GHz multi-modulus prescaler is presented for implementing phase locked loop. The circuits were fabricated 0.13 ¿m CMOS process. The measured results showed good agreement with simulation data demonstrating good modeling accuracy of CMOS active and passive devices for millimeter-wave applications.
