摘要
提出一种新型高速低工作电压的嵌入式flash灵敏放大器,该灵敏放大器由一个新型的位线稳压器和一个折叠共射-共基放大电路组成.基于0.13μm标准CMOS单元库的仿真结果表明,该灵敏放大器在-40℃~150℃的温度范围内有快速的读取速度,在最差工作环境下读取时间为17ns,最佳工作环境下为10ns,常温1.2V条件下的读取时间为12.5ns.
A new high-speed low-supply voltage sense amplifier,which is composed of a new bit-line voltage regulator and a folded cascode ampligier circuit,is presented. It has been verified that the read speed of the new sense amplifier is fast in temperature range from-40℃ to 150℃ by simulation with 0.13μm CMOS models. Simulation results showed a read time of 17ns for the worst case,10ns for the best case,12.5ns and the normal temperature/1.2V case,respectively.
