Abstract As the switching speeds and densities of Digital CMOS integrated circuits continue to increase, output switching noise becomes more of a problem. This paper reports a novel design technique which aids in the reduction of switching noise. The output driver stage is analyzed through the use of an equivalent RLC circuit. The results of the analysis are used in the design of an output driv...
This study aims to design analog-to-digital converter based on successive approximations (SAR ADC), with very low power consumption, in an advanced CMOS technology (28 nm), following the industrial methodologies IC. This project was conducted in partnership with Synopsys, operating at a supply voltage of 0.5 V ± 10% with a resolution of 12 bits and 500 kS/s sampling frequency. Keywords— Analog-...
The design of a low power digital VLSI CMOS integrated circuit for the measurement of signals in the range [10, 300] Hz is presented. The architecture performs a delay calculation in order to determine the bearing angle of a sound source. Restrictions regarding power dissipation are to be improved against a previous implementation, while keeping computing accuracy. A Verilog RTL preliminary imp...
This paper presents and discusses digital pixel readout integrated circuit architectures for long wavelength infrared (LWIR) in CMOS technology. Presented architectures are designed for scanning and staring arrays type detectors respectively. For scanning arrays, digital time delay integration (TDI) is implemented on 8 pixels with sampling rate up to 3 using CMOS 180nm technology. Input referre...
CMOS RF has evolved from a novelty to a necessity with the mergence of all analog and digital functionality into a single chip for standards such as Bluetooth and WLAN/802.11. The stringent performance requirements associated with cellular standards such as GSM, however, has either limited the level of RF transceiver integration, or compelled the use of alternative technologies such as BiCMOS o...
An electronic nose (E-Nose) is one of the applications for surface acoustic wave (SAW) sensors. In this paper, we present a low-noise complementary metal-oxide-semiconductor (CMOS) readout application-specific integrated circuit (ASIC) based on an SAW sensor array for achieving a miniature E-Nose. The center frequency of the SAW sensors was measured to be approximately 114 MHz. Because of inter...
Systems-on-chips (SoCs) that combine digital and high-speed communication circuits present new opportunities for powersaving designs. This results from both the large number of system specifications that can be traded off to minimize overall power and the inherent low capacitance of densely integrated devices. As shown in this paper, aggressively scaled silicon-oninsulator (SOI) CMOS is a promi...
The wide bandgap of silicon carbide (SiC) has attracted a large interest over the past years in many research fields, such as power electronics, high operation temperature circuits, harsh environmental sensing, and more. To facilitate on complex integrated SiC ensure reproducibility, cut down cost, availability low-voltage technology for circuits is paramount importance. Here, we report scalabl...
The present paper proposes analog integrated circuit (IC) implementation of a biologically inspired controller in quadruped robot locomotion. Our controller is based on the central pattern generator (CPG), which is known as the biological neural network that generates fundamental rhythmic movements in locomotion of animals. Many CPG-based controllers for robot locomotion have been proposed, but...
The analog IC technology, might sound old-fashioned, is still important for the future wireless systems such as 4G cellular phone systems, broadband wireless networkings, and wireless sensor networkings. The analog features and issues of the scaled CMOS transistor, the basic issue and the technology trend for the ADC as an important building block of wires systems, and the feature of the digita...
