传统的阻抗测量解决方案包括复杂的电子数据采集电路设计,由许多分立元件组成。通常需要这种电路来产生频率分布并获得该激励频率的响应。其中包括一片用于产生激励频率的DAC,以及与其它的信号调理元件协同工作的同步采样ADC。此外,系统必须保持线性,所以需要考虑误差以及温度对多元件的影响。这种方法需要很长的开发和评估时间,从而影响到面市时间。
Traditional impedance measurement solutions include complex electronic data acquisition circuit design, composed of many discrete components. This type of circuit is often required to generate a frequency distribution and obtain the response of the excitation frequency. This includes a DAC that generates the excitation frequency and a synchronous sampling ADC that works in conjunction with other signal conditioning components. In addition, the system must be linear, so the effects of errors and temperature on multiple components need to be considered. This method takes a long time to develop and evaluate, which affects the time to market.
