The One

In this paper, a novel architecture for self-timed analog-to-digital conversion is presented and designed using the NULL Convention Logic (NCL) paradigm. This analog-to-digital converter (ADC) employs successive approximation and a one-hot encoded masking technique to digitize analog signals. The architecture scales readily to any given resolution by utilizing the one-hot encoded scheme to permit identical logical components for each bit of resolution. The four-bit configuration of the proposed design has been implemented and assessed via simulation in 0.18-μm CMOS technology. Furthermore, the ADC may be interfaced with either synchronous or four-phase asynchronous digital systems.

Hardware Circuit

An applied hardware circuit for detecting the AGC signals isolated with DSP is designed based on a high-linearity analog optocoupler. The problem of narrow measuring scope, low linearity and instability which caused by noisy signals is resolved when collects industrial analog signals into DSP. The practical circuit with proper design of components is designed through repeated experiments. The experiment data are analyzed by the method of least-square. The analyzed results show this circuit has the high accuracy and good linearity.

To match, test, and determine the working conditions and correctness of each function of the aircraft measurement system. This article proposes a design of equivalent test platform which can produce digital and analog signals for the self-testing of measurement system. By using the ethernet protocol chip W5300 to achieve the high-speed communication between host computer and equivalent device. Communication uses UDP unicast data transfer mode with advantages of high-speed and long-distance transmission, and the Phenomenon of data packet loss is not easy in transmission.

The article deals with the practical aspects of synchronization and data transferring in multichannel phased array systems, especially in systems with big antenna dimensions. In multichannel passed array antenna commonly used an optical analog signals distribution scheme for RF and heterodyne signals and wired interfaces for control and digital data. For modern digital antennas the data transferring and synchronization method, based on digital fiber optic channels, was presented. The schemes, constructions, and algorithms of the method are described. The method was realized as SDR system using FPGA with soft-processor core. For data transferring the 8b/10b code is used. The following result of experiment are discussed: digital optical lines are resistant to signals distortions, can transfer big data massive with minimal delay, have excellent synchronization capabilities at quite low cost.
