Abstract

This paper presents the design and implementation of a bandpass filter with very low insertion losses (<;0.5dB) for cellular transmitters, with 0dBm capabilities. In order to obtain a high integration of the filter with existing fully digital architectures, it has been designed in CMOS 65nm technology. This filter takes full advantage of previously developed highly linear and high Q active inductors in CMOS. We present a design methodology based on filter frequency reconfigurability (1.72.1GHz) while preserving linearity and low insertion losses on this wide frequency range.
