Full-duplex crystalless CMOS transceiver with an on-chip antenna for wireless communication in engine controller board of hybrid electric vehicles

A full-duplex transceiver for wireless inter-chip data communication in an engine controller board of hybrid electric vehicles that for the first time integrates an on-chip antenna and a duplexer, as well as allowing operation without a crystal frequency reference is demonstrated. The BER degradation of RX due to the TX operation is negligible when the input power is greater than -44 dBm necessary to achieve BER of less than 10
^-12
. The transceiver fabricated in 0.13 μm CMOS consumes 245 mW.
