Future cellular systems have attracted considerable interest in millimeter-wave and terahertz frequency bands for wireless communication. Power consumption is one of the most significant technical obstacles for practical receivers, and it is even more crucial for mobile devices. This study employs a general methodology to comprehend the tradeoff between power consumption and system performance. Targeting potential 6G cellular applications, we evaluate a fully-digital beamforming architecture at 140 GHz with a 2 GHz sample rate. In 90 nm SiGe BiCMOS, we devise alternative designs for key radio-frequency (RF) components, such as the low-noise amplifier (LNA), mixer, local oscillator (LO), and analog-to-digital converter (ADC). Using the proposed framework and detailed circuit and system simulations, we can select the design option that accomplishes the optimal overall trade-off between end-to-end performance and power consumption. The analysis identies crucial design decisions and constraints.Low-power front-ends are typically comprised of low-resolution ADCs and low-power mixers, which reduce the system’s dynamic range. The relatively low dynamic range, which then exposes the receiver to adjacent carrier interference and blockers, is a critical but less studied consequence of these designs. We present a general mathematical framework for analyzing the efficacy of mmWave front-ends in the presence of out-of-band interference in this thesis. The objective is to reveal the fundamental tradeoff between power consumption, interference tolerance, and in-band performance. Detailed network simulations in cellular systems with numerous carriers and detailed circuit simulations of critical components at 28 and 140 GHz are coupled with the analysis. The analysis identies weak spots in low-power interference robustness and recommends design enhancements for use in real-world systems.Finally, we report the development of MIMO receiver array tile modules operating at 135 GHz. The module integrates four or eight RF channels on an LTCC carrier, with each channel containing a 22 nm SOI CMOS IC for RF-baseband and a linear microstrip patch antenna array; DC, baseband IQ and LO reference signal connections are made via a printed circuit board attached to the LTCC carrier. Digital beamforming is demonstrated using an 8-element array with a 3-dB beam width of 12◦ and an angular steering range of 56◦, and a 4-element array with a 3-dB beam width of 12◦ and an angular steering range of 20◦ prior to the appearance of grating lobes. In single-beam operation, the 4-element arrays exhibit 15.7 dB RMS error vector magnitude when receiving 1.34 Gb/s QPSK data and 5.6 dB RMS error vector magnitude when receiving 1.92 Gb/s 16-QAM data.
