| 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 do-main.The reference voltage required for data recovery Was adaptively generated to extend the range of the input data rate.The design Was validated using 0.25μm CMOS technology.With 45.5 kbits/s input data,the entire circuit only consumes less than 13μW of power. |
| Keywords: | integrated circuit complementary metal oxide semiconductor(CMOS) clock and data recovery pulse position modulation charge pump low power design |
