Abstract :
A compact energy transmission system in 40nm standard CMOS is presented. The system consists of a 60GHz VCO followed by a quad-core power amplifier as transmitter and an RF-to-DC converter as receiver. The total power delivered by the quad-core PA to its four 50Ω loads is 24.6dBm. The receiver is a complementary cross-coupled rectifier with a measured efficiency of 28% while supplying 1mA of current. The system can support amplitude and frequency modulations and beam-forming capabilities for wireless applications with minimal front-end complexities.
