用第三代电流传送器设计n阶有源滤波器
Novel nth-order active filter employing third-generation current conveyor
摘要
Abstract
A design method for current-mode wth-order universal filter based on CCIII was presented, the design formula derivation was performed. The wth-order high-pass, low-pass and band-pass filters were obtained by the design method. The circuits consisted of n CCIII+ and 2 n passive components were analyzed, the passive and active sensitivities of the two-order high-pass, low-pass and band-pass filter circuits are both low. For example, when pole angular frequency was 106rad/s, the circuit was simulated with PSPICE. Results show that high-pass filter cut-off frequency is 790 kHz, low-pass filter cut-off frequency is 149 kHz and band-pass filter center frequency is 139 kHz. Data show that the design theory is correct and the design method is feasible.关键词
