摘要

A fully integrated 750~960 MHz wireless transceiver (TRX) is presented for single-tone NB-IoT applications. Effective design methodologies and techniques, from the system level to circuit level, are proposed to address various design challenges while achieving low-power consumption. The TRX consists of a low-IF receiver with 180-kHz signal bandwidth, a digital polar transmitter with 3.75-kHz signa...
