This letter presents a 60 GHz wideband differential driving amplifier based on multi-section coupled lines (MSCL) matching network for the first time. The impedance transforming of the proposed two-port matching network is realized in a single structure. It is suitable for millimeter wave CMOS integrated circuit design since the proposed matching network eliminates the self-resonant and defected-ground problems which exist in the traditional transformer or inductor based matching networks. It provides an inherent DC-block function and is compact in size compared with the conventional transmission line based matching technique. Using the proposed network, a differential amplifier in 65 nm CMOS is designed, measured and discussed. Wideband and high gain performance is achieved.
