低电压低功耗CMOS 5Gb/s串行收发器

设计并实现了一种使用0.13μm CMOS 工艺制造的低电压低功耗串行收发器.它的核心电路工作电压为1V,工作频率范围为2.5~5GHz.发送器包括一个20:1的串行器和一个发送驱动器,其中发送驱动器采用了预加重技术来抵消传输信道对信号的衰减,降低信号的码间串扰.接收器包括一个输入信号预放大器,两个1:20的解串器以及时钟恢复电路.在输入信号预放大器中设计了一个简单新颖的电路,利用前馈均衡来进一步消除信号的码间串扰,提高接收器的灵敏度.测试表明,收发器功耗为127mW/通道.发送器输出信号均方根抖动为4ps.接收器在输入信号眼图闭合0.5UI,信号差分峰-峰值150mV条件下误码率小于10-12.

A Low Voltage Low Power CMOS 5Gb/s Transceiver

A low voltage and low power SerDes transceiver implemented in 0.13μm CMOS is described.The power supply voltage is 1V,and the operating frequency range is from 2.5 to 5GHz.The transmitter includes a 20∶1 serializer and a transmission driver,the latter of which uses pre-emphasis architecture for channel compensation.The receiver employs two 1∶20 deserializer,an input signal pre-amplifier,and a clock and data recovery circuit.The pre-amplifier employs a novel architecture,consisting of a feed-forward equalizer to cancel ISI.The measured transceiver power consumption is 127mW/channel.The RMS jitter of the transmitter output is 4ps.Test results indicate the receiver BER is less than 1e-12 when the input signal amplitude is 150mV differential peak to peak and the eye closure is 0.5UI.
