Millimeter-wave and Terahertz communications consist of complex analog and mixed-signal transceivers where overall system performance is often limited by the weakest performing subsystem. While analog and mixed-signal integrated circuits have significantly advanced, the future of 5G and 6G transceiver design could be accelerated by including artificial intelligence. In this combination, analog integrated circuit design and operation would harness machine learning to identify, characterize, and act upon variations and anomalies in system performance. Focusing on 5G and 6G, this paper investigates solutions for a unified intelligent integrated transceiver: a conceptual combination of a traditional analog subsystem, a supporting digital subsystem that enables artificial intelligence, and dedicated feedback circuitry or sensors that monitor performance, efficiency, or reliability. Active and passive components and propagation channels are reviewed based on their merits of introducing intelligence. Holistically and for broader applicability, the paper conceptualizes and coins the notion of an "intelligent integrated system (IIS)", which brings forward a novel unified vision and approach toward context-aware subsystems that dynamically interact with ambient and varying operating conditions. To demonstrate viability, the paper concatenates a select set of measurement results.

“…The SiGe technology with its high f T (Krithivasan et al , 2006) makes high performance mm-wave integrated circuits commercially viable, though there has been a growing interest in developing mm-wave integrated circuits at low cost in CMOS technology (Sandstrom et al , 2010). The IBM 8HP process is a 0.13 μm SiGe BiCMOS process (Mabuza and Sinha, 2013), which offers high performance SiGe HBTs with f t of 200 GHz. The process also offers modelled radio frequency (RF) passive devices for mm-wave designs, like the Lange coupler.…”

Purpose -The demand for higher bandwidth has resulted in the development of mm-wave phased array systems. This paper explores a technique that could be used to feed the individual antennas in a mm-wave phased array system with the appropriate phase shifted signal, to achieve required directivity. It presents differential Colpitts oscillators at 5 GHz and 60 GHz that can provide differential output signals to quadrature signal generators in the proposed phase shifter system. Approach -The phase shifter system comprises a differential Colpitts voltage controlled oscillator (VCO) and utilizes the vector-sum technique to generate the phase shifted signal. The differential VCO is connected in the common-collector configuration for the 5 GHz VCO, and is extended using a cascode transistor for the 60 GHz VCO for better stability at mm-wave. The vector-sum is achieved using a variable gain amplifier (VGA) that combines the in-phase and quadrature phase signal, generated from oscillator output using hybrid Lange couplers. The devices were fabricated using IBM 130 nm SiGe BiCMOS process, and simulations were performed with a process design kit provided by the foundry. Findings -The measured results of the 5 GHz and 60 GHz VCOs indicate that differential Colpitts VCO could generate oscillator output with good phase noise performance. The simulation results of the phase shifter system indicate that generation of signals with phases from 0° to 360° in steps of 22.5° was achieved using the proposed approach. A Gilbert mixer topology was used for the VGA and the linearity was improved by a pre-distortion circuit implemented using an inverse tanh cell. Originality/value -The measurement results indicate that differential Colpitts oscillator in common-collector configuration could be used to generate differential VCO signals for the vector-sum phase shifter. The simulation results of the proposed phase shifter system at mm-wave shows that the phase shift could be realised at a total power consumption of 200 mW.
