N2 - This paper provides a filtered power-distribution network (PDN) approach to improve the detection sensitivity of low-power and resource-constrained wireless receivers. We study the power supply-induced artifacts and perform extensive simulations and experimental measurements that reveal significant performance improvement of the receiver front-end, reflected in the noise figure and bit-error rate specifications throughout the receiver chain. Using an experimental setup based on Commercial-Off-The-Shelf (COTS) components, the proposed PDN design applied to a commercial Low-drop-out (LDO) regulator reduces the supply noise, integrated over 2.4 GHz, by 12.5 dB and suppresses the peak-to-peak voltage variation by 45 mV. The supply voltage enhancement results in ≥10 dB signal-to-noise ratio (SNR) improvement in the receiver chain and contributes to higher current data speeds and stability at the end user.
