摘要
用于多标准(蓝牙，WCDMA/UMTS和WLAN)可重构接收器的模拟基带链在0.25 μ m CMOS中使用1.65 mm。该结构由一个开环可编程增益放大器(PGA1)、一个有源gm - rc低通滤波器(LPF)和一个闭环可编程增益放大器(PGA2)组成。链增益可编程在-10divide68dB范围内，而输入参考噪声(IRN)为5nV/radicHz。在线性度方面，该器件在UMTS模式下具有21dBm的带内输出参考互调截距点(OIP3)，在WLAN模式下具有1.3 dBm的1dB压缩点。总谐波失真(THD)为1%，动态范围(DR)大于78 dB。电流消耗被最小化，并根据不同的操作条件进行调整，整个链条的电流消耗降至11 mA。
A 5nV/√Hz-IRN, 78dB-gain-range, 78dB-DR multi-standard baseband chain for Bluetooth, UMTS and WLAN
An analog baseband chain for a multistandard (Bluetooth, WCDMA/UMTS, and WLAN) reconfigurable receiver in a 0.25 mum CMOS uses 1.65 mm . The structure is composed by an open-loop programmable-gain amplifier (PGA1), an active-Gm-RC low-pass filter (LPF), and a closed loop programmable-gain amplifier (PGA2). The chain gain can be programmed in the range -10divide68dB, while the input-referred noise (IRN) is 5nV/radicHz. In terms of linearity, the device features an in-band output referred intermodulation intercept point (OIP3) of 21dBm in UMTS mode, and a 1dB compression point of 1.3 dBm in WLAN mode. A dynamic range (DR) larger than 78 dB is achieved for a 1% total harmonic distortion (THD). The current consumption is minimized and adjusted for the different operation conditions, down to 11 mA for the full chain.
