A 05-V BLE Transceiver With a 19-mW RX Achieving 964-dBm Sensitivity and 27-dBm

Abstract

This article presents a 0.5-V RF transceiver fully compliant with Bluetooth low energy (BLE) standards. The receiver (RX) fabricated in a 22-nm fully depleted silicon on insulator (FD-SOI) process achieves a sensitivity of −96.4 dBm, an intermodulation tolerance of −27 dBm for interferers at 6- and 12-MHz offsets, while consuming 1.9 mW. An RX- chain with a gain-programmable low-noise transconductance amplifier (LNTA) provides good linearity over a wide input power range. The LNTA changes amplifie
