Comparators are very important circuits that can be found in a variety of applications, especially comparators whose reference level can be controlled. In this paper, a voltage‐controlled comparator whose reference voltage is controlled by a control voltage and a programmable comparator whose reference voltage is controlled by an input bit pattern are presented. These two comparators are analyzed quantitatively. The performance of the two proposed comparators is verified by simulation using the Berkeley predictive‐technology models (BPTM) of the 45‐, 32‐, 22‐, and 16‐nm complementary metal‐oxide semiconductor (CMOS) technologies with power‐supply voltages, V_DD, of 1, 0.9, 0.8, and 0.7 V, respectively. The proposed controlled comparator is compared with the conventional latch‐type comparator from the points of view of the response time, the output amplitude, and the power consumption.

基于逆变器的电压控制和可编程比较器

比较器是非常重要的电路，可以在多种应用中找到，特别是可以控制参考电平的比较器。本文提出了一种电压控制比较器，其参考电压由控制电压控制；可编程可编程比较器，其参考电压由输入位模式控制。对这两个比较器进行定量分析。通过使用具有电源电压的45、32、22和16纳米互补金属氧化物半导体（CMOS）技术的伯克利预测技术模型（BPTM）进行仿真，可以验证两个建议的比较器的性能。，V _DD分别为1、0.9、0.8和0.7V。从响应时间，输出幅度和功耗的角度，将建议的受控比较器与常规锁存型比较器进行比较。
