SiGe BiCMOS Integrated Circuits and Systems for Sub-THz Communication and Sensing

This talk provides a comprehensive overview of ASICs across the entire G-band, developed by the Circuit Design Department of IHP for a broad range of applications, such as high-data-rate wireless communication, radar, sensing, and spectroscopy. System architecture and silicon realization will be illustrated and discussed in detail for multiple complete transceiver systems: a 110–170GHz four-channel transceiver front-end, suitable for ultra-wideband data transmission and capable of delivering 200Gbps over a wireless link in one of its variants; a wideband 256GHz radar transceiver chip, designed for integration in large MIMO arrays driven with a sub-harmonic reference in a multi-chip daisy-chain configuration; fully-integrated modular 2×4 beamforming transmitter and receiver ICs for 220–260GHz wireless data transmission up to 50Gbps. Additionally, circuit blocks suitable for communication and sensing at 220–320GHz will be presented, including power amplifiers and active fundamental mixers for direct up- and down-conversion.
