This paper presents a method to design optimized local control strategies for Cyber-Physical Systems that produce reliable data models for social applications. Data models have different semantics and abstraction levels. The local control strategies manage ad-hoc nano-clouds of embedded computing and communication nodes (CCNs) used for data collection, modeling, and communication. Control strategies...
A 14-bit 100-MS/s pipelined ADC in 0.18 mum 1P6M CMOS process is presented. A new sampling technique is introduced which achieves high linearity over wide bandwidth by eliminating the major sources of distortion at low and high input frequencies. The ADC uses digital background calibration, featuring a shuffled-dithering scheme, to obtain a DNL of +0.18/-0.18 LSB and an INL of +1.1/-0.6 LSB. It achieves...
A novel low-voltage two-stage operational amplifier employing class-AB architecture is presented. The structure utilizes level-shifters to create the class-AB behavior in the first and second stages. With this structure, the transconductances (gm) of the two stages are double compared with the normal configuration without class-AB behaviors with the same current consumption. Thus power can be saved...
In this paper, we consider bandwidth fusion to improve the range resolution. We propose a method based on spectral estimation and amplitude-phase error model to compensate for the lack of mutual coherent between radar subbands. Then we consider two-dimensional fusion to improve the range and cross-range resolution. A new algorithm, called EMEMP, is developed to resolve the poles mismatch occurred...
