Abstract:

Towards the emerging AI era, IoT is becoming more important. Current IoT wireless nodes require replacement or recharging of the battery. This is impractical when a massive number of nodes are connected to the network. Ultra-low-voltage wireless connectivity that can operate with power supplied from energy harvesters, for example 0.5V from solar cells, is necessary [1]. BLE is a good candidate, but a high blocker resilience in the 2.4GHz ISM band is required even though the BLE specifications are not strict compared to other standards. It is a challenge to design RX circuits at low voltage without sacrificing performance, especially blocker resilience and sensitivity.
