Abstract
A 280 μW current-reuse, sub-threshold balun low noise amplifier (LNA) is presented for medical radio device communication (MedRadio) over the frequency range of 401- 406 MHz. An exemplary balun LNA is designed in a UMC 0.18- μm CMOS technology. The differential conversion of RF input has been procured by stacking power phase splitter (PPS) on top of the inductively degenerated common-source (IDCS) technique. The proposed balun LNA accomplish voltage gain of 19 dB, input & output isolation is less than -14 dB, noise figure of 4.1 dB and IIP3 of -15dBm while consuming 280 μA from 1V supply. The gain & phase error between differential outputs is 1 dB & 0.60 respectively. The layout area of proposed balun LNA core is 0.988mm2.
