摘要
提出了一个用频变负阻作为有源元件实现的无源梯形低通网络结构 ,而频变负阻只需要两个第二代电流传送器和三个无源元件 .
A passive gradient low-pass network configuration employing two frequency-dependent negative resistors (FDNRs) as active elements is proposed. and FDNR requires only two second generation current conveyors and three passive elements. Such active RC low-pass network preserves the low sensitivity character of the passive prototype network.
