我們設計低電壓寬擺幅第二代電流傳輸器並應用在一個不敏的Butterworth二階低通濾波器上。電路使用TSMC 1P4M 0.35 um製程。CCII(1)最小的供應電壓為|Vtp|+3Vod，CCII(2)最小的供應電壓為|Vtp|+2Vod，兩個CCII的擺幅均為軌對軌。

We developed low voltage wide swing second generation current conveyors(CCII) with the application to a insensitive Butterworth second-order low-pass filter. All circuits are designed using the parameters of TSMC 1P4M 0.35um process. The minimum supply voltage of CCII(1) circuit is |Vtp|+3Vod. The supply voltage of CCII(2) circuit is |Vtp|+2Vod. The voltage swing of the CCIIs are almost rail to rail.
