Abstract: The applications of internet of things (IoT) are increasing exponentially in the day-to-day life. Similarly, usage of artificial intelligence (AI) applications in the IoT devices, improves efficiency and selectivity with the penalty of additional power consumption for data processing. Therefore, the DC power consumption of IoT radio is a critical design specification, and it directly influences the battery life and usage. Recently, both academia and industry are involved in developing such radio at low power with various innovative receiver and transmitter architectures. The Bluetooth low energy (BLE) and ZigBee transceivers at 2.4 GHz are suitable for IoT applications with relaxed specification requirements. This paper presents a review of the various low power ZigBee/BLE receiver architectures, and circuit design techniques suitable for AI-enabled IoT applications that include low voltage, sub-threshold, and current reuse. Similarly, the circuit design techniques in the on-off shift keying (OOK) receivers for IoT and wake-up applications are presented.

Keywords: IoT; artificial intelligent; receiver; ZigBee; Bluetooth low energy; BLE; on-off shift keying; OOK; low power; wake-up.
