Abstract

This paper presents on-chip balun with capacitors connected in series (BCCS) has three-order high pass frequency characteristic. It can be used to suppress the power spectral density (PSD) of UWB impulse radio (UWB-IR) signal within 0.96-1.61 GHz. With proper value of capacitor, BCCS has sharper cutoff edge than the balun without capacitor connected, which is desired for UWB-IR transmitter. The balun is fabricated in 0.18μm CMOS technology and tested. Its effectiveness to suppress the PSD of UWB-IR transmitter is demonstrated.
