摘要
准浮栅MOS晶体管的工作原理、电气特性及等效电路的系统采用TSMC 0.25μm 2P5M CMOS工艺的CMOS准浮栅技术,提出了0.8 V运算放大器,最大直流开环增益可以达到76.3 dB,相位裕度为75°,单位增益频率为1.0 5 MHz.设计了0.8 V一阶CMOS开关电容高通滤波器,滤波器输入输出电压范围为0～0.8 V,截止频率为100 KHz.
Based on the analysis of the principle, electric characteristic and equivalent circuits of quasi floating-gate transistors, a novel 0. 8V OPA and 0. 8 V Rail-to-Rail analog switch are proposed in TSMC 0. 2Stem 2PSM CMOS technology,the DC open-loop gain of the amplifier is 76.3dB, the phase margin is 75° and the unit gain width is 1.05 MHz. A 0.8V CMOS switch capacitor high pass filter is presented, and the simulated results show that filter＇s input and output characteristic is Rail-to-Rail.
