REALIZATION OF NEW CURRENT-MODE LOWPASS AND BANDPASS CIRCUIT

本文提出了用改进的第二代电流传送器(CCCⅡ)综合出二阶电流模式低通和带通滤波器的通用电路,电路的频率ω_0和品质因素Q能独立调节,为了验证电路的可行性,给出了低通和带通滤波器的PSPICE仿真结果,该通用电路有低的无源灵敏度。

In this paper, a general circuit which synthesizes second-order current-mode lowpass and bandpass filter using the modified second generation current conveyor(CC Ⅱ(?)) is suggested. The frequency, ω_0, and the quality factor, Q, of this circuit can be adjusted separately. To verify the feasibility of the proposed circuit, the PSPICE simulation results are given. This general circuit has low passive sensitivities.
