摘要:

采用TSMC 0.25 μm CMOS工艺,设计了一种2.4 GHz CMOS低中频结构的蓝牙射频接收机前端.整个接收机前端包含全差分低噪声放大器、混频器以及产生正交信号的多相滤波器.叙述了主要设计过程并给出了优化仿真结果.采用Cadence SpectreRF进行仿真,获得了如下结果:在2.5 V工作电压下,中频输出增益为21 dB,噪声系数为7 dB,输入P 1 dB为-21.3 dBm,IIP3为-9.78 dBm,接收机前端总的电流消耗为16.1 mA.

Abstract:

A 0.25 μm CMOS RF receiver frontend for Bluetooth in TSMC 0.25 μm CMOS process is designed. It includes a differential LNA, two mixers and a polyphase filter that generates a quadrature signal. The receiver frontend is simulated with Cadence SpectreRF. The supply voltage is 2.5 V, gain of the receiver front-end is 21 dB, noise figure is 7 dB, P 1 dB is -21.3 dBm, IIP3 is -9.78 dBm, and the total current is 16.1 mA.
