| Abstract: | Analogue forepart filter technology to enhance performance in low voltage power line communication is researched. This paper proposes a design for filter module. This module includes high-pass elimination filter and band pass filter.The former finishes removing the synchronized noise , the latter realizes passing signal of the band and straining disturbance. The novel element CCIII (the third generation current conveyor) is used to design the band pass filter.The proposed scheme belongs to an active filter circuit ,and it is easy to integrate. It is proved that the scheme is able to work at high frequency point and in wide band excelling conventional active filter via PSpice simulation result waves. The filter is close to an ideal current source so that it works stably on any loads. And this scheme is feasible because the sensitivity values of the important performance parameter is low. |
