摘　　要：提出了一种新型的带有阈值电压失配补偿能力的电压灵敏放大器,该结构可实现对电压信号的快速灵敏放大以及输入端的补偿。在SMIC0.15μm1P5MlogicCMOS工艺条件下,较传统灵敏放大器结构,该灵敏放大器可在基本维持相同功耗和面积水平的同时,将延迟降低至23ps,并能够在50mV的阈值电压失配条件下正常工作,显著地提高了失配补偿能力,从而提高了芯片成品率。A new voltage mode sense amplifier with the ability of threshold voltage mismatch self-compensating is presented. Compared with the conventional structure on condition of SMIC 0.15 μm 1 PSM logic CMOS process, the delay of new sense amplifier is 23 ps, while the penalties of area and power consumption are neglectable. The proposed sense amplifier is in normal operation while there is a V, mismatch of 50mV, so that the yield is improved too because of the application of mismatch self-compensating structure.
