摘要

我们提出了在深亚微米CMOS中用于3G极性发射机的完全集成相位路径的首次发表的实现和测量。它包括一个单四频带数字控制振荡器(DCO)，提供调制能力来处理WCDMA相位(频率)数据的宽带和一个开关逆变器分频器。完整的芯片集成了ldo，从1.4V电源消耗20mA，同时在40MHz偏置下为2GHz输出提供-157dBc/Hz的PN

Quad Band Digitally Controlled Oscillator for WCDMA Transmitter in 90nm CMOS

We present the first published implementation and measurements of a fully integrated phase path for a 3G polar transmitter in deep sub micron CMOS. It includes a single quad band digitally controlled oscillator (DCO) providing modulation capability to handle the wide bandwidth of the WCDMA phase (frequency) data and a switched inverter divider. The complete chip, with integrated LDOs, consumes 20mA from a 1.4V supply while providing a PN of -157dBc/Hz at a 40MHz offset for a 2GHz output
