本指南详细介绍了Cadence-Spectrum软件中的各种函数及其使用方法,旨在帮助用户更好地理解和应用相关功能,提升设计效率。
SpectrumThe Spectrum assistant is used to plot and calculate the Fast Fourier Transform (FFT) of a periodic waveform, along with various measurements such as Signal-to-Noise-and-Distortion Ratio (SINAD), Spurious Free Dynamic Range (SFDR), Effective Number of Bits (ENOB), and Signal-to-Noise Ratio (SNR without distortion). It also calculates ENOB, SINAD, SNR, SFDR, THD, sigpower, thddb, totalharmpower, peakharmpower, snb, snrh, dcpower for a given input signal. These spectrum measures are used to characterize A-to-D conversion.
