Correction method for a single chip power meter 一种单片功率计的校正方法
H. Nagura, K. Fujino
The single chip power meter is a programmable mixed signal IC for three phase power line measurement. The DSP block includes two programmable 32 bit processors which executes metering functions and calibration algorithm for six AD converter inputs. In the calibration algorithm correction methods for two major errors have been attempted: for a non-linearity error of input transformers and AD converters, for a phase leading error of the current transformers against the voltage transformers. 30 correction coefficients including frequency dependency are computed by an automatic calibration system. The experimental results demonstrate the efficiency of the corrections: the non-linearity of RMS current measurement has been reduced from /spl plusmn/0.17%FS to /spl plusmn/0.07%FS by the nonlinearity correction, the measurement offset error of three phase power has been reduced from /spl plusmn/3%FS to /spl plusmn/0.25%FS by the phase error correction. These correction techniques bring a breakthrough for cutting the production cost, by permitting use with inexpensive transformers which have less linearity and large characteristic deviation.<>
单片机功率计是一种用于三相电力线测量的可编程混合信号集成电路。DSP模块包括两个可编程的32位处理器,用于执行六个AD转换器输入的计量功能和校准算法。在校准算法中,尝试了两种主要误差的校正方法:输入变压器和AD转换器的非线性误差,电流互感器对电压互感器的相位超前误差。通过自动校准系统计算了包括频率相关性在内的30个校正系数。实验结果证明了校正的有效性:通过非线性校正,可将RMS电流测量的非线性从/spl plusmn/0.17%FS减小到/spl plusmn/0.07%FS;通过相位误差校正,可将三相功率的测量偏移误差从/spl plusmn/3%FS减小到/spl plusmn/0.25%FS。这些校正技术为降低生产成本带来了突破,允许使用线性度较小、特性偏差较大的廉价变压器。

An abnormal phenomenon due to substrate bias modulation in the integrated PIN photodiode sensor with dielectric isolation 介电隔离集成PIN光电二极管传感器中由于衬底偏置调制引起的异常现象
M. Kyomasu, T. Suzuki, K. Okajima, M. Sahara
An abnormal phenomenon was found in the integrated PIN photodiode sensors (which is named PIN Photo Integrated Circuits Sensor: PIN-PICS) combined with a bipolar IC in the same substrate. It was observed in the optical device called "2 electric wires type photoelectric sensor". It occurs at the time to drive the external LED by internal timing generator. This phenomenon was investigated by three methods, that is, the failure analysis the measurement of device parameters and both circuit and device simulations. These results show that the problem was induced from the PIN structure forming PIN-PICS. When the switching noise was altered, the most of this noise was transferred to preamplifier through parasitic capacitance of the PIN photodiode connected with a P/sup +/tab across a P-layer, and it distorted the output waveform of preamplifier by differential components. Therefore, in order to prevent this phenomenon, it's necessary to exchange the connection of parasitic capacitance from P/sup +/tab to substrate. We confirmed that an Au back metallization of 3000 /spl Aring/ thickness, or Au-Si alloy die bonding is the most effective.<>
在同一衬底上集成PIN光电二极管传感器(称为PIN光集成电路传感器:PIN- pics)与双极IC结合时发现了一种异常现象。观察到的光学装置称为“2电线式光电传感器”。它发生在内部定时发生器驱动外部LED的时候。通过故障分析、器件参数测量以及电路和器件仿真三种方法对这一现象进行了研究。结果表明,该问题是由PIN结构引起的。当开关噪声发生改变时,大部分开关噪声通过P/sup +/tab跨P层连接的PIN光电二极管寄生电容传递到前置放大器,并通过差分分量使前置放大器输出波形发生畸变。因此,为了防止这种现象,有必要将寄生电容从P/sup +/tab到基板的连接进行交换。结果表明,采用3000 /spl /厚度的Au背面金属化或金硅合金模具结合是最有效的。

I.B. Yarovkin, Yu.N. Vlassov, A. Kozlov, N.S. Pashchin
The design and performance of two types of SAW pressure sensors have been considered. SAW resonator oscillators with metal strip gratings designed for operation at 200 and 360 MHz have been used in both type devices to study the opportunity of the mechanical pressure measurement became of mechanical loading on Rayleigh surface wave propagation. Such electrical characteristics of SAW resonator as amplitude and phase response are discussed, as well as a geometrical dimensions of the sensitive element and a disposition of SAW structures on it. The sensitivity and the non linearity of both sensors with a sensitive element shaped as an integral crystal diaphragm and sensor with mechanically loaded quartz plates measured and discussed too. Experimental data clearly show that sensitivity and threshold are not independent parameters for this kind of pressure sensor. We studied the opportunity to optimize this parameters for a given pressure range. Finally, recommendations are made for optimal configuration of SAW pressure sensor according to pressure and dynamic range demands. These results are important for the design of SAW pressure sensors intended for operation in gaseous or liquid media.<>

Jen-Dau Lin, Kung-Hung Kuo, C. Yeh
In this paper, we have developed a phase-domain model to analyze a nonlinear fiber-optic gyroscope (FOG) system theoretically, and use it to obtain an optimal-designed system. System's design including details of signal processing is described here and used to improve system's sensitivity and precision. From computer's simulation and experimental results, we know that 1. The experimental results coincide with the analytic results, with error less than 4% in the respects of rise time, overshooting, and steady state error; that is proved by the computer simulation for the time domain response of a step and a ramp input tests. 2. Using the phase-domain model, one can build up one's optimal FOG system with zero steady state error, 6% overshooting, high stability, and short rise time about one of system's natural frequency, i.e. 1spl omegasub n/.<>

Estimation of heat sources and temperature distribution by boundary integral method 用边界积分法估计热源和温度分布
S. Inoue, M. Ohmichi, T. Hashimoto
A simple evaluation of boundary integral in the inverse problem of the steady state heat conduction system is proposed. The boundary values of temperature and its gradient are computated from the direct analysis using FDM and the results of inverse analysis from these boundary values are compared with the given FDM parameters to give the reasonable estimation of boundary integrals. We show that the temperature gradient has some leaks from Dirichlet boundary region by the incomplete derivation of temperature gradient on the boundary surface. The 0.5 mesh extrapolation of temperature gradient from Dirichlet boundary region is also shown to give the accurate boundary integrals in the case of relatively coarse data points of boundary values. This 0.5 mesh extrapolation method is applicable to the actual inverse analysis of three dimensional system.<>
