Abstract

A 2.4GHz TX in 65nm CMOS defines three channels using three high-Q FBARs and supports OOK, BPSK and MSK. The oscillators have -132dBc/Hz phase noise at 1MHz offset, and are multiplexed to an efficient resonant buffer. Optimized for low output power ≈-10dBm, a fully-integrated PA implements 7.5dB dynamic output power range using a dynamic impedance transformation network, and is used for amplitude pulse-shaping. Peak PA efficiency is 44.4% and peak TX efficiency is 33%. The entire TX consumes 440pJ/bit at 1Mb/s.

一个440pJ/bit 1Mb/s 2.4GHz多通道fbar TX和一个集成脉冲整形PA

采用65nm CMOS的2.4GHz TX使用三个高q fbar定义了三个通道，并支持OOK, BPSK和MSK。振荡器在1MHz偏置时具有-132dBc/Hz相位噪声，并复用到有效的谐振缓冲器。针对低输出功率≈-10dBm进行了优化，采用动态阻抗变换网络实现7.5dB动态输出功率范围，并用于幅度脉冲整形。峰值PA效率为44.4%，峰值TX效率为33%。整个TX以1Mb/s的速度消耗440pJ/bit。
