All cell circuits such as analog multiplier, seeking small and sum, divider were implemented on8 AN221E04s, and then an intact controller was assembled with the cell circuits. 在8块AN221E04芯片中实现模拟乘法器、求小求和以及除法等单元电路,由各单元电路组合成完整的控制器。
The comparison of digital frequency divider and traditional analog frequency divider shows that the former is more superadded. 比较了数字分频器与传统模拟分频器,说明数字分频器更具优点。
In indirect tension control, the calculating of roll diameter 、 dpomic and statics compensation current of tension is complex. By using analog multiplier and divider, there will be large error and drift and therefore it difficult to implement accurate tension control. 间接张力控制系统中,卷径D、动静态张力补偿电流计算复杂,用模拟乘除器实现起来误差大、漂移严重,很难实现精确的张力控制。
This paper introduces a kind of nonlinear-carrier ( NLC) controller for high power factor boost converters. Using the NLC controller, input line voltage and current sensing, error amplifier in the current shaping loop, and analog multiplier/ divider are eliminated. 阐述了一种非线性载波(Nonlinear-carrier)控制的PFC电路,该电路与传统单级功率因数校正电路相比不再需要输入电压、电流采样以及复杂的模拟乘法器和电流误差放大器电路。
Because EBG structure can reduce the surface wave, the antenna radiation performance has been significantly improved. Then, the thesis introduces a microstrip reflection-type analog phase shifter and Wilkinson power divider, and the detailed design processes of them are presented. 接着,本文设计了微带反射式模拟移相器和Wilkinson功分器,文中给出了详细的设计过程,并对其进行实物加工。
