摘要:
设计一种超低功耗、适用于脉冲位置调制的时钟数据恢复电路.通过对电荷积分,将窄脉冲的时间间距转化为电压,可便捷地恢复精确同步的时钟和数据信号.为扩大可工作的数据率范围,数据恢复所需阈值电压根据输入信号自适应产生.采用CMOS 0.25 μm工艺实现所设计的电路,通过仿真验证了其性能.该设计在输入数据率为45.5 kbit/s时,电路功耗仅为13 μW.
Abstract:
An extremely low power clock and data recovery circuit was designed for pulse position modulated input.Synchronized clock and data were recovered through converting the timing distance between pulses into voltage domain.The reference voltage required for data recovery was adaptively generated to extend the range of the input data rate.The design was validated using 0.25 μm CMOS technology.With 45.5 kbits/s input data,the entire circuit only consumes less than 13 μW of power.
