Abstract-An active balun using current steering for phase correction is presented. The proposed active balun is constructed with two different unit balun structures based on current steering to reduce phase and amplitude errors. This type of topology can be compared with the conventional phase and amplitude correction techniques which do not incorporate the current steering. Designed and fabricated active balun in 0.18 μm CMOS process operates over 0.95 -1.45 GHz band, showing input reflection coefficient under -15 dB, phase error of 11˚ and gain error of 0.5 dB. Gain is measured to be 0.3 dB maximum and power consumption of 7.2 mW is measured.

“…Among the various topologies of active baluns [12][13][14], the commonly used topology is the differential amplifier topology. As shown in Figure 1(a), a conventional differential amplifier can be used as an active balun.…”

“…In hybrid circuits passive baluns are commonly used [8][9][10][11], while in RFIC and MMIC designs both active baluns and passive baluns are widely implemented. For ICs work below 4 GHz, since the passive baluns are too bulky to realize on chip, usually active baluns are implemented [12][13][14]. For ICs work above 4 GHz, compared with active baluns [15,16], passive baluns are more intensively studied, such as lumped-element baluns [17], transformer baluns [18][19][20] and Marchand-type baluns [21][22][23][24].…”

Abstract-Compact K-Band CMOS baluns are designed, fabricated and characterized in a 130 nm CMOS technology. These baluns include a tunable active balun, a L-C lumped element balun, and two asymmetric planar transformer baluns. The detailed design processes are presented, including the topology selection, the transistor, inductor and transformer sizing, and the layout considerations. These topologies are compared in various aspects such as insertion loss, phase and amplitude imbalance, bandwidth, chip area, power consumption, and the difficulty to design and integration. An impedance tuning approach is implemented to chose the proper balun topology and to simply the balun integration. The baluns are on-wafer characterized and the measurement results compare the state-of-the-art realizations.

“…Hence, the design of a UWB LNA is more challenging than a traditional narrow-band LNA. Furthermore, wideband receivers typically incorporate single-ended inputs (Mastantuono & Manstretta, 2009) that remove the loss of the passive balun but also deteriorate the second-order distortion. In order to compromise these limitations, a single-ended LNA with a following active balun is implemented.…”
