Abstract

A 780-MHz low power RF transceiver for wireless nodes in IoT (Internet of Things) applications was designed and implemented in 65nm CMOS process. Direct-Digital modulation and regeneration configured receiver are adopted in the RF transceiver. Measurement shows that the transceiver can provide a data rate from 100Kbps to 1Mbps (peak data rate can be up to 2Mbps). With a 1.2 V DC supply, the transmitter can present 3 emission levels (-9dBm,-1dBm, 4dBm) and the corresponding power consumption is from 4.3 to 9.6mW. The receiver can present -65dBm sensitivity at a BER of 0.001 with 3.75mW power consumption. The chip size is 1mm², and the whole transceiver is integrated in high level with minimized external components.
