非晶态硅Forouhi-Bloomer模型参数拟合计算
半导体材料对光的吸收作用用k表示。材料的k一般都会随着入射光的波长的改变而改变。其变化规律因材料而异,但是对于同一类型的材料常可以用一种模型来表示。但是对于特定的材料,其模型参数的确定常的通过曲线拟合的方法得到的。
题目:
对于非晶态的硅,其K满足如下模型:
其中A、B、C为系数,且均大于零,并满足4C-B2>0 Eg为禁带宽度,值为1.3 ev , E为能量。
现已知一组E对应的K值,通过曲线拟合的方法求出A,B,C。(Curve fitting)

FPGA-DESIGN-OF-A-HARDWARE-EFFICIENT-PIPELINED-FFT
The digital wideband receiver is a critical component in modern digital receivers. The receiver has the capability to expose and distinguish adverse signals contained within a large bandwidth (on the order of 1 GHz or more) of the radio frequency (RF) spectrum. The spectral estimator is a highly important design element imperative to the detection of the hostile signals within the intended bandwidth in order to fulfill mission requirements. This crucial element of an FFT-based digital receiver presented several challenges in the development of this research. The task at hand was to minimize the total hardware consumption contributed to the complex arithmetic operations while maintaining a high single signal spurious-free dynamic range (SFDR) and multi-tone instantaneous dynamic range (IDR).
