本论文对国内外的模拟低电压低功耗技术做了广泛的调查研究,分析了这些技术的工作原理和优缺点,在吸收这些技术成果基础上设计了一个1 . 5v低功耗轨至轨cmos运算放大器。在设计输入级时,为了使输入共模电压范围达到轨至轨,不是采用传统的差动输入结构,而是采用了nmos管和pmos管并联的互补差动输入对结构,并采用成比例的电流镜技术实现了输入级跨导的恒定;在中间增益级设计中,电流镜负载并不是采用传统的标准共源共栅结构,而是采用了适合在低压工作的低压宽摆幅共源共栅结构;在输出级设计时,为了提高效率,采用了推挽共源级放大器作为输出级,输出电压摆幅基本上达到了轨至轨;本论文改变传统基准源基于运放的设计,采用了带电流镜负载的差分放大器设计了一个基准电流源,给运放提供稳定的偏置电流和偏置电压,保证了运放的稳定性;并采用了带调零电阻的密勒补偿技术对运放进行频率补偿。
