A 24-GHz Transmitter with an On-Chip Antenna in 130-nm CMOS

A transmitter with an on-chip dipole antenna operating in the 24-GHz ISM band was fabricated in 130-nm CMOS. It provides 8-dBm output power and 7.7% rms EVM while consuming 100-mW power. An integer-N synthesizer consuming 36-mW power is also integrated. The signal transmitted by the chip has been picked up 95 m away using a horn antenna. This work demonstrates that communication between a base station and an integrated circuit with on-chip antenna over a distance of 100 m is possible
