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.

Abstract The design, manufacturing and DC and microwave characterization of high-power Schottky barrier InAlAs/InGaAs back-illuminated mesa structure photodiodes are presented. The photodiodes with 10 and 15 μm mesa diameters operate at ≥40 and 28 GHz, respectively, have the output RF power as high as 58 mW at a frequency of 20 GHz, the DC responsivity of up to 1.08 A/W depending on the absorbing layer thickness, and a photodiode dark current as low as 0.04 nA. We show that these photodiodes provide an advantage in the amplitude-to-phase conversion factor which makes them suitable for use in high-speed analog transmission lines with stringent requirements for phase noise.

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.
