With reference to an architecture for the full integration of a 60 GHz receiver in embedded systems with wireless gigabit connectivity, the paper presents the design of key building blocks such as: on-chip antenna, low noise amplifier (LNA) and a time-interleaved fast A/D converter (ADC) with AMBA AXI interface towards the digital baseband part. With respect to the state of the art the co-design of the on-chip antenna with the LNA, and the fast ADC architecture realized as a time-interleaved array of threshold-configuring SAR channels, represent new solutions optimized in terms of power consumption. Complexity and performance results in a 65-nm CMOS SOI technology, suitable also for digital systems integration, are presented. The performance and complexity results of the designed antenna, LNA and ADC are integrated in a system level simulator with those obtained by adopting known solutions for other receiver blocks (mixer, IF and baseband amplifiers and filters, frequency synthesizer) thus estimating the performance achievable with a whole 60 GHz receiver and digitization sub-system macrocell. The system-level estimated performances confirm the feasibility of a full-integrated receiver supporting short-range High Definition (HD) connectivity of several Gb/s with a Signal-to-Noise-Ratio compliant with WiGig and Wireless HD new standardization initiatives.

A 240-GHz monostatic circular polarized SiGe frequency-modulated continuous wave radar system based on a transceiver chip with a single on-chip antenna is presented. The radar transceiver front-end is implemented in a low-cost 0.13 µm SiGe HBT technology version with cut-off frequencies fT/fmaxof 300/450 GHz. The transmit block comprises a wideband ×16 frequency multiplier chain, a three-stage PA, while the receive block consists of a low-noise amplifier, a fundamental quadrature down-conversion mixer, and a three-stage PA to drive the mixer. A differential branch-line coupler and a differential dual-polarized on-chip antenna are added on-chip to realize a fully integrated radar transceiver. All building blocks are implemented fully differential. The use of a single antenna in the circular polarized radar transceiver leads to compact size and high sensitivity. The measured peak-radiated power from the Si-lens equipped radar module is +11 dBm (equivalent isotropically radiated power) at 246 GHz and noise figure is 21 dB. The characterization bandwidth of the radar transceiver is 60 GHz around the center frequency of 240 GHz, and the simulated Tx-to-Rx leakage is below −20 dB from 230 to 260 GHz. After system calibration the resolution of the system to distinguish between two targets at different distance of 3.65 mm is achieved, which is only 21% above the theoretical limit.

Due to the growing demand on high performance and low power in embedded systems, many core architectures are proposed the most suitable solutions. While the design concentration of many core embedded systems is switching from computation-centric to communication-centric, Network-on-Chip (NoC) is one of the best interconnect techniques for such architectures because of the scalability and high communication bandwidth. Formalized and optimized system-level design methods for NoC-based many core embedded systems are desired to improve the system performance and to reduce the power consumption. In order to understand the design optimization methods in depth, a case study of optimizing many core embedded systems based on 3-Dimensional (3D) NoC with irregular vertical link distribution topology through task mapping, core placement, routing, and topology generation is demonstrated in this chapter. Results of cycle-accurate simulation experiments prove the validity and efficiency of the design methods. Specific to the case study configuration, in maximum 60% vertical links can be saved while maintaining the system efficiency in comparison to full vertical link connection 3D NoCs by applying the design optimization methods.
