This paper presents on-chip balun with capacitors connected in series (BCCS) which is used for designing Ultra Wideband Impulse Radio (UWB-IR) transmitter. UWB signal is strictly limited especially between 0.96-1.61GHz to avoid interfering with GPS by Federal Communications Commission (FCC). BCCS has high-pass characteristic, and attenuates the power spectral density (PSD) of UWB signal within low frequency band. Hence, BCCS is very suitable for designing UWB-IR transmitter. BCCS is fabricated in 0.18μm CMOS technology and tested, and the effectiveness for high-pass characteristic is confirmed.
