Internet of Things (IoT) and Artificial Intelligence (AI) has been in a rising trend, and has led to innovation, such as Artificial Intelligence Internet of Things (AIoT). Edge devices, commonly used for data collection, requires to be always turned-on. Often, power consumption is a key factor in AIoT as devices are operated by batteries. Event triggered edge devices consist of a sensor, for sensing purposes. Comparator makes up the key architecture. Since the AIoT devices are event trigger, power consumption should be as low as possible. However, this degrades the performance of the devices. In this project, a nanowatt power consumption comparator is designed operating in standby mode. To ensure that device also operate even due to noise, hysteresis will also be implemented in the design. Comparator designed consumed a static power consumption of 51.67nW and have a hysteresis voltage of ±5mV. Maximum bandwidth of comparator is 1kHz.
