This thesis aims to design transformer-based balanced passive components with high performance and compact size using CMOS and printed-circuit¡Vboard (PCB) technologies. A CMOS parallel-combining transformer (PCT) incorporating a planar trifilar transformer is presented to realize power combining and impedance transformation at the same time. In addition, a CMOS Wilkinson power combiner with a planar bifilar transformer is proposed to enhance isolation between two combining ports. Several transformer coupled balun designs with an overlay winding structure are carried out on FR4 and Duroid substrates. These designs uses a rather symmetric layout to achieve a superior balance performance and a multilayer configuration to create the transmission zeros in the out-of-band response. Finally, a CMOS transformer balun is implemented with a bandpass filter passband which is designed according to the coupled resonator filter theory. This passband can restrict the bandwidth usage for the balun to improve the common-mode rejection ratio (CMRR) within the passband.
