In this paper, we describe design and implementation of the Dependable Responsive Multithreaded Processor (D-RMTP) SoC (System-on-a-Chip) and SiP (System-in-a-Package). The D-RMTP SoC provides almost all functions required for the humanoid robots, including a real-time processing unit, a real-time inter-node communication link with error correction, and various I/O peripherals. The D-RMTP SoC is implemented...
The design of integrated circuits, especially system-on-chips (SoC) is now constrained by many parameters such as speed, energy but also the robustness to process variability. Indeed, controlling the speed and the energy in a complex SoCs - which adopt the globally asynchronous locally synchronous (GALS) paradigm - require specific power supplies and clock generators as actuators and dedicated sensors...
This paper describes the design of a system-on-a-chip (SoC) that integrates ADC, DAC, DDC and DDS blocks for communication system applications. Special considerations are given to the noise, power and ground, ESD and packaging design to ensure design success. The described chip has been manufactured and achieved first time silicon success.
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
While the CMOS analog circuits can be designed with the minimum-gate-length of the fabrication process in the alpha-power law MOSFET model, the length of a MOSFET gate has been chosen to be a larger scale than the minimum-gate-length in the conventional Shockleypsilas square model. In this paper, we describe a 6-b 100 MSPS CMOS current steering digital-to-analog converter (DAC) with the alpha-power...
