Optimization of Hardware Overhead in Continuous Checksum-Based Analog Error Detection Circuit

基于连续校验和的模拟检错电路硬件开销的优化

We analyzed FFT spectrum of ideal analog data with quantity error, theoretical data with nonlinear error and error from limit slew rate of amplifier. We also analyzed FFT spectrum of data with combined errors.

介绍了理论模拟数据的FFT频谱分析，分别研究了量化误差、由放大通路的有限压摆率所引起的误差和非线性误差对信号频谱的影响以及它们之间的相互叠加后的频谱。

After calculating the analog to digital convert error, each stage processes the next stage input signal immediately, and this increases the value of output signal flow speed.

每一级电路计算完它的模拟转换误差后，马上就可以对下一个输入数据进行计算，提高了随机数产生速度。

Chapter 4 describes the theory of interpolating circuit that uses analog circuit to turn error pulses to voltage. The design of interpolating circuit and devices selection is introduced in this section too.

第四章阐述了利用模拟电路将误差脉冲转化为电压量的内插电路原理，论述了电路的设计及器件参数的选择。
