| 摘 要： | 工作在亚阈值状态的MOS晶体管具有极小的工作电流和类似于双极型晶体管的指数特性,因此适合于实现微功耗的外部线性内部非线性电流型电路.为了适合于低电源电压的运用,本文给出了一种新型的电流型四象限乘法器以及滤波器,振荡器等基本单元电路,并利用标准0.6-μm CMOS的工艺参数以锁相环为例进行了性能模拟验证.

| Abstract: | Due to their micro operating current and exponential nature,the subthreshold MOS transistors are suitable to implement current-mode micro-power externally linear circuits.In this paper,a novel current-mode four-quadrant multiplier is proposed and the design techniques and considerations on basic modules for low-voltage micro-power applications,such as filters,oscillators,etc.,are given.To verify the performance,a PLL is designed and simulated as an example with the model of standard 0.6μm 5V CMOS process. |
