基于数字可编程电流控制电流传输器的通用滤波器

Abstract

本文采用电流分配网络(CDN)和电流控制电流传输器(CCCII)实现了数字可编程电流传输器(DPCCCII)，与传统的电流控制电流传输器相比，该器件可通过编码的方式来改变CCCII中的寄生电阻(Rx)，从而可以实现数字可编程的功能。本文采用DPCCCII为有源器件实现了一种多功能的数字可编程滤波器电路，并对该滤波器进行了非理想分析以及蒙特卡洛分析。PSPICE的仿真结果验证了该电路的可行性和正确性。 The implementation of digitally programmable generation current controlled current conveyor (DPCCCII) is based on the current distribution network (CDN) and the second generation current controlled current conveyor (CCCII) in this paper. Compared with existing the second generation current controlled current conveyor, the device has the characteristics of digital programmable, by encoding the way to change the parasitic resistance in CCCII (Rx). In this paper, a multi-function digital programmable filter circuit is implemented with DPCCCII as active device, and the filter is analyzed by non-ideal and Monte Marlo. The validity of the proposed circuit was verified through PSPICE simulations.
