一个带反馈的低压低功耗比较器的设计

为解决比较器的低压低功耗的问题,将低压和反馈等电路技术应用到比较器的设计中.开展比较器的电路结构与功耗的分析,在比较器中只使用一个重生的锁存器,使比较器能在低压下工作,此外,使用动态反馈的技术,当比较器比较结束时,由数字逻辑判断电路检测并关闭比较器,使比较器只消耗动态功耗,因而有效地降低了比较器的平均功耗.使用Cade...

Design of low-voltage and low-power comparator with feedback

In order to solve the problems of low-voltage and low-power comparator,the circuit technology of low voltage and feedback was investigated.The circuit structure and power consumption of the comparator were analyzed.The comparator can be used in low voltage by using only one regeneration latch.And only the dynamic power consumption was consumed.By the digital logic detection circuit,the comparator was detected and shutten down.When the comparison was over,the average power consumption of the comparator was reduced efficiently.At last,the low voltage comparator with feedback was simulated by Cadence.The simulation results show that the low voltage comparator with feedback is suit for low voltage with very low power consumption.
