摘要

An ultralow-power direct-conversion Bluetooth-low-energy (BLE) receiver (RX) front-end that employs current-reuse and subthreshold techniques is presented. A stacked and self-biased low-noise amplifier (LNA) with active balun consumes $400~\mu \text{W}$ and achieves a noise figure (NF) of 3.2-dB and a high gain (programmable from 18 to 31 dB), meeting the system specifications over the process, ...
