Abstract :
We hereby report the design and measurements of a 101-118 GHz 65 nm CMOS transmitter. The transmitter architecture is based on a two-step upconversion using a single 80 GHz LO with the quadrature phases generated by injection locked frequency dividers. Both BPSK and QPSK modulations with a maximum datarate of 20.6 Gbps are supported. A measured output power of -5 dBm at 115 GHz and an error-vector magnitude of 17.5% for 30 dB conversion-loss downconversion link are obtained. The chip core area is 0.21 mm2 and a DC power consumption of 280 mW.
