摘要
在低电压、低功耗电流模式信号处理电路设计中 ,电流镜是必不可少的器件。他不仅实现电流信号的复制或倍乘 /倍减 ,极性互补的电流镜还可以实现差动单端电流信号的交换 ,还可提供高输出阻抗以便产生稳定的电流。在本文双极型电流镜的改进电路中 ,通过利用复合管的放大作用 。
In low power current mode signal processing circuits, it is often necessary to use current mirrors to replicate and amplify/attenuate current signals, and it can exchange signals from one port to two ports It can provide stable current with high output impedance A new dipolar transistor circuits are designed which is efficient to decrease the following error
