Large-area current source arrays are widely used in current-steering digital-to-analog converters (DACs) to statistically maintain a required level of matching accuracy between the current sources. This not only results in large die size but also in significant degradation of dynamic range for high-frequency signals. To overcome technology barriers, relax requirements on the layout, and reduce ...

This study is devoted to in situ temperature measurement in diamond anvil cells (DACs) with intelligent anvils (i-anvils). I-anvils consist of diamonds implanted with B and/or C ions, situated below the diamond's surface at a depth of 1-3 microm; forming sensors which are placed below the culet at the location of the DAC's sample chamber. I-anvils can be employed as temperature or pressure sens...

Analog-to-digital converters (ADCs) and digital-toanalog converters (DACs) play an important role in the design of data acquisition systems. ADCs are used to convert analog signals like the output from a temperature transducer, a radio receiver or a video camera into digital signals for processing. Conversely, DACs are used to convert digital signals back to analog signals. For example, the DAC...

Recent improvements in the speed and complexity of commercially available digital signal processing (DSP) devices have allowed digital techniques to be extended to a number of new areas. Now many applications in RF and communications are within the bandwidth capability of current generation DSP systems. This paper demonstrates a system developed recently for such applications. It uses standard ...

This paper introduces a new digital adaptive background technique to jointly compensate for the analog impairments of frequency and time-interleaved sections jointly frequency-time interleaved digital-to-analog converters . architecture consists hierarchical structure lower bandwidth converters...

Tunnel lighting is the most significant component in total energy consumption whole infrastructure. Hence, various control strategies based on light-emitting diode (LED) technology have been investigated to conserve by decreasing luminaires’ operating time. In this study, four kinds of tunnel and development their associated technologies are evaluated: no-control low-consumption lamps (LCL), ti...
