全集成多功能MOSFET－C CCII连续时间滤波器的设计

本文提出了一种以第二代电流传输器（ＣＣＩＩ）作为基本单元的集成ＭＯＳ－ＦＥＴ—Ｃ多功能连续时间滤波器。它可以实现诸如低通、带通、高通二次传递函数。该电路不采用平衡结构,但ＭＯＳ管的非线性的消除程度则等同平衡结构。灵敏度也较低。

Optimization of reluctance accelerator efficiency by an improved discharging circuit

In this paper, an improved discharging circuit was proposed to quicken the decay of the current in the drive coil in a reluctance accelerator when the armature reaches the center of the coil. The aim of this is to prevent the suck-back effect caused by the residual current in drive coil. The method is adding a reverse charging branch with a small capacitor in the traditional pulsed discharging circuit. The results under the traditional circuit and the improved circuit were compared in a simulation. The experiment then verified the simulations and they had good agreement. Simulation and experiment both demonstrated the improved circuit can effectively prevent the suck-back effect and increase the efficiency. At the voltage of 800 V, an efficiency increase of 36.34% was obtained.
