CMOS differential active balun circuit small-signal analysis
Frederick Ray I Gomez, Maria Theresa G De Leon, John Richard E Hizon
The paper presents a study of a differential active balun circuit in terms of the small-signal analysis, implemented in a complementary metal-oxide semiconductor (CMOS) technology. It is important to analyze the small-signal or alternating current (AC) response or frequency response of the active balun to determine the maximum frequency of operation and the effective bandwidth of the designed circuit. This is to ensure that the designed active balun circuit would normally produce gain or attenuation at the desired frequency of operation. Eventually, design tradeoffs are inevitable and are carefully considered in the analysis and design.
