中文摘要 | 在此篇論文中,兩個使用單一COA (Current Operational amplifier)所製成方波產生器將被實現。COA是一個擁有兩個電流輸入端和多個電流輸出端的主動元件。 這些電路將有以下數個優點:(1)輸入端的寄生電容幾乎等於零,(2)輸出的信號是電流模式,(3)頻寬範圍較大,(4)週期是可以調整的這個電路將以AD844這個IC模型來模擬。 |
英文摘要 | In this paper, two square wave generators using a COA are presented. A COA (Current Operational amplifier) is an active device with two current input terminals and many current output terminals. The circuits have several advantages: (1) the parasitic capacitors of input terminals approach zero, (2) the output signal is current, (3) the frequency range is wide, (4) the period is adjustable. The proposed circuits are simulated with the model of the AD844 IC. |
