—This paper presents a 60-GHz direct-conversion RF front-end and baseband transceiver including analog and digital circuitry for PHY functions. The 65-nm CMOS front-end consumes 319 and 223 mW in transmitting and receiving mode, respectively. It is capable of more than 7-Gb/s 16QAM wireless communication for every channel of the 60-GHz standards, which can(More)
SUMMARY An L-2L through-line de-embedding method has been verified up to millimeter wave frequency. The parasitics of the pad can be modeled from the L-2L through-line. Measurement results of the transmission lines and transistors can be de-embedded by subtracting the parasitic matrix of the pad. Therefore, the de-embedding patterns, which is used for(More)
— This paper presents a 16QAM direct-conversion transceiver in 65 nm CMOS, which is capable of 60-GHz wireless standards. The capacitive cross-coupling neutralization contributes a high common-mode rejection and a high reverse isolation, and a fully-balanced mixer can improve the error vector magnitude due to the reduced local leakage. The maximum data(More)
—This paper proposes the method of varactor cross-couplng with adaptive bias. The capacitive cross-coupling neu-tralization contributes to improve power gain and reverse isolation. The optimized capacitance of cross-coupled PA depends heavily on the input power. Thus, the varacter is used and adaptive bias is obtained by the feedback of the input power. The(More)
At 60 GHz, it becomes difficult to achieve a high power added efficiency (PAE) and large output power for CMOS power amplifier (PA). A parallel class-A and AB pseudo Doherty PA is designed in CMOS 65 nm process to obtain a high PAE and large output power. The PA achieves a 9.8-dB gain at 60 GHz. The measured large signal results show that a maximum power(More)
This paper presents a 60 GHz direct-conversion transmitter in 65 nm CMOS technology. The power amplifier consists of 4-stage transistors. The circuit model of de-coupling capacitor is built as a transmission line to consider the physical length. In the measurement results, the conversion gain is above 9.6dB at 58--65GHz band, and the 1 dB compression point(More)
