This paper proposes thermometer-code latches having five and six transistors for unidirectional and bidirectional thermometer-code shift-registers, respectively. The proposed latches omit the set and reset transistors by changing from two supply voltage nodes to the set and reset signals in the cross-coupled inverter. They set or reset the data by changing the supply voltage to ground in either of two inverters. They reduce the number of transistors to five and six compared with the conventional thermometer-code latches having six and eight transistors, respectively. The proposed thermometer-code latches were simulated using a 65 nm complementary metal-oxide-semiconductor (CMOS) process. For comparison, the proposed and conventional latches are adapted to the 64 bit thermometer-code shift-registers. The proposed unidirectional and bidirectional shift-registers occupy 140 μm² and 197 μm², respectively. Their consumption powers are 4.6 μW and 5.3 μW at a 100 MHz clock frequency with the supply voltage of 1.2 V. They decrease the areas by 16% and 13% compared with the conventional thermometer-code shift-register.

用于温度计代码移位寄存器的 5-T 和 6-T 温度计代码锁存器

本文提出了分别用于单向和双向温度计代码移位寄存器的具有五个和六个晶体管的温度计代码锁存器。所提出的锁存器通过将交叉耦合反相器中的两个电源电压节点更改为设置和重置信号来省略设置和重置晶体管。它们通过改变两个逆变器中任何一个的接地电源电压来设置或重置数据。与分别具有六个和八个晶体管的传统温度计代码锁存器相比，它们将晶体管的数量减少到五个和六个。建议的温度计代码锁存器使用 65 nm 互补金属氧化物半导体 (CMOS) 工艺进行模拟。为了比较，建议的和传统的锁存器适用于 64 位温度计代码移位寄存器。分别为²和 197 μm ²。在 100 MHz 时钟频率和 1.2 V 电源电压下，它们的功耗分别为 4.6 μW 和 5.3 μW。与传统的温度计代码移位寄存器相比，它们的面积减少了 16% 和 13%。
