Abstract

In this paper, an ultra-low-power 2.45GHz mixer-first 1ow-IF receiver front-end is presented. To have extremely low power consumption, a technique for implementing an on-chip low-power local oscillator is proposed that contains a 9-stage pseudo-differential ring oscillator operating at 1/9 of the RF frequency. As well as reducing the power consumption, this technique results in having a lower 1/f 3 phase noise corner frequency. The proposed front-end is fabricated in GF22nm FDSOI technology. It consumes 50 μ W and has 2x less power than the state-of-the-art while having competitive calculated sensitivity of -84dBm for 1MHz GFSK demodulation.
