We implemented a wireless synchronization receiver using sub-8psec pulses. A novel self-mixing technique is introduced to detect low-power picosecond impulses and extract the repetition rate with a low timing jitter. The chip is fabricated in a 0.13μm SiGe BiCMOS process and achieves a time transfer accuracy of 376fsec. The receiver , which is integrated with a broadband on-chip antenna, successfully detects a picosecond pulse train with a 3.1GHz repetition rate and generates an output locked to this rate with a phase noise of -89 dBc/Hz at 100 Hz frequency offset. The chip consumes 146 mW from a 2.5V supply and occupies an area of 1.89mm^2.
