资料介绍

探讨了一种频率补偿电路,将一个在高频部分衰减了的“模拟某传感器特性的电路模块”高频部分补偿回来,所有频率补偿部分都采用了模拟电路方案来实现。传感器特性的电路模块的模拟高性能音频运算放大器0PA2134,能够做到超低失真,低噪声音频应用完全指定。整个补偿模块实现了在频率达到100kHz时衰减,并在70kHz前没有明显波动,最后用MSP430f5438a低功耗单片机显示输出峰值及对应波形。

This paper probes into a frequency compensation circuit, which compensate the attenuated high frequency part of a circuit module simulating a sensor's features, all frequency compensation parts were realized by adopting the artificial circuit scheme. The artificial high-performance audio operational amplifier 0PA2134 of the circuit module with sensor's features can realize ultra-low distortion, and the application of low noise audio is fully specified.The whole compensation module realizes the attenuation in the frequency of 100 kHz, and has no obvious fluctuation before 70 kHz, and finally output the peak value and the corresponding waveform through the display of the low-power single-chip microcomputer MSP430f5438a.
