Obtaining sufficient EVM in all four 1.76GHz bandwidth channels specified by IEEE 802.15.3c and the emerging 802.11ad high-data-rate wireless communication standards for modulations as complex as QAM16 is a challenge. Recently reported implementations are therefore restricted to just 1 or 2 channels [1]. Wireless applications often use digital low-power(More)
Power and substrate domains are strategically isolated or unified in heterogeneous 3D integration. In-tier probing circuitry provides accessibility to power delivery and substrate networks in a deep tier of a 3D chip stack and capability of diagnosing intra/inter tier coupling. A two-tier demonstrator was successfully tested in a 130 nm CMOS, 3DSIC Cu TSV(More)
The availability of 9GHz bandwidth around 60GHz in combination with simple modulations schemes, low-cost radio ICs and small antenna size, allows for multi Gbit/s wireless communications. In this article the potential of 60GHz wireless communications is evaluated from system, application and user point of view. Further, design challenges for 60GHz CMOS(More)
To enable mass-market applications based on shortrange wireless communication around 60 GHz at datarates above 1 Gbps, cheap implementation technologies are needed. The radios for these applications often use antenna arrays with beamforming to improve the link budget. This work discusses the state-of-the-art on CMOS beamforming architectures and describes(More)
