摘　　要：本文提出了由单电流控制传输器(current controlled conveyor)实现的新型二阶低通滤波器,该滤波器是交流耦合,结构简单,功耗低,带宽约5MHz,适用于WCDMA的直流变频接收机。A new second-order filter based on a single current controlled conveyor (CCCII) is presented. The filter is AC coupled and has about 5 MHz bandwidth, Moreover, the filter has low power consumption, simple configuration, small size, making it suitable for implementing the baseband filter of a WCDMA direct-conversion wireless receive.
