The area penalty, operation stability, and operation speed of the 20-nm-ZG FinFET SRAM were compared to those of the 20-nm-ZG bulk-planar SRAM. The FinFET SRAM with beta-ratio of 1 is expected to realize not only 7% less area penalty, but also the same or superior operational stability to that of the bulk-planar SRAM with beta-ratio of 2 because of less variability of the device performance. Also,...
A low power ultra-wideband impulse radio (UWB-IR) receiver was developed in 0.18-mum CMOS. All circuits of the receiver AFE operate intermittently with a sampling clock of an analog-digital converter (ADC). The sampling rate of the ADC is equal to the pulse repetition frequency of the received signals. Power consumption of the receiver AFE is reduced by 60% using a developed intermittent operation...
A tagless location system is proposed and experimentally demonstrated. The delay profile of UWB impulse radio can be detected easily because of its nanosecond pulse width. This profile appears as spatial information such as the location of a person. The profile is influenced by the propagation environment. Therefore, we can use the delay profile associated with specific location information as an...
