Ultra-low Voltage Embedded Memories – Design Aspects and a Biomedical Use-case
As the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent. A research-proven approach to achieve ULP consumption is to aggressively lower the supply voltage (VDD) below or in the vicinity of the transistor threshold voltage (Vth) and operate the transistors in the subthreshold (sub-Vth) region. Operating below or near the threshold voltage, i.eAs the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent.
