摘要
针对已有的传统整流器,其滤波性能与无源元件的精度、温度变化特性密切相关等的缺点,尝试采用基于开关电容技术的现场可编程模拟阵列(FPAA)芯片AN221E04来实现一个调节简便、成本低的整流滤波器的设计。该设计充分利用了FPAA的优点,提高整流器的精度,减弱温度、电压漂移。且在FPAA中可动态可调控,进一步提高处理的精度和效果。
Existing traditional rectifier has a shortcoming that its filter performance is closely related to the accuracy of passive components and the temperature changes and so on.To overcome these shortcomings,this study tries to achieve the design of the rectifier using the field programmable analog chips（FPAA）AN221E04based on the technology of switching capacity.The rectifier is regulation simple,low-cost commuting filter.The design makes full use of advantages of FPAA to improve the precision of the rectifier,abate drifts of temperature and voltage.Dynamic-controling quality factor can be easily used in the FPAA,which can further improve the accuracy and effectiveness.
