摘要

提出了一种采用弱反转技术设计的0.9 V、0.5 /spl mu/A的轨对轨CMOS运算放大器。耗尽模式NMOS晶体管缓冲块驱动PMOS差分对以实现宽输入动态范围，而输出级架构通过使用低压跨线性控制电路提供对称轨对轨输出驱动。

A 0.9 V, 0.51 /spl mu/A rail-to-rail CMOS operational amplifier

A 0.9 V, 0.5 /spl mu/A, rail-to-rail CMOS operational amplifier designed with weak inversion techniques is presented. Depletion-mode NMOS transistors buffer a bulk-driven PMOS differential pair to realize wide input dynamic range, while the output stage architecture provides symmetric rail-to-rail output drive through the use of a low voltage translinear control circuit.
