Samenvatting
This paper presents a wakeup receiver for latency-critical IoT applications in 90nm CMOS, which is fully compliant to many popular IoT wireless standards with constant envelope modulations, such as Bluetooth Low Energy and IEEE802.15.4. Paired with a standard-compliant transmitter, the proposed wakeup receiver method minimizes the overhead in system power, area and complexity. The proposed 2-dimensional wakeup pattern reduces the latency of a wakeup event to below 100μs. Supplied at a battery voltage of 2V, the chip fully integrates a power management unit, a wakeup receiver with offset and noise suppression, a low power digital baseband with automatic gain control and RSSI estimation, and a crystal oscillator. With a BLE compliant signal, the chip achieves -58dBm sensitivity, and a >600s mean time without false alarm, consuming 195μA.
