摘　　要：灵敏放大器作为静态随机存储器中的重要设备,其稳定性会影响信息的输入和读出的准确性,从而对静态随机存储器的性能造成较大影响。针对传统的灵敏放大器很难准确地控制高电平脉冲持续时间的问题,本论文设计了一种新型灵敏放大器。该灵敏放大器由锁存型放大电路、脉冲产生子电路和脉冲结束判决子电路组成。新型灵敏放大器能够自动调节脉冲宽度以达到适应锁存型放大电路系统的工作要求,大大地提高了灵敏放大器的可靠性。As an important device in static random access memory,the stability of sensitive amplifier affects the accuracy of information input and readout,thus having a great impact on the performance of static random access memory.In this thesis,a new type of sensitive amplifier is designed to address the problem that conventional sensitive amplifier is difficult to accurately control the duration of high level pulses.The sensitive amplifier consists of a latching amplifier circuit,a pulse generation sub-circuit and an end-of-pulse judgment sub-circuit.The new sensitive amplifier can automatically adjust the pulse width to meet the operating requirements of the latching amplifier system,and greatly improve the reliability of the sensitive amplifier.
