A 12.5-Gb/s On-Chip Oscilloscope to Measure Eye Diagrams and Jitter Histograms of High-Speed Signals

A 12.5-Gb/s on-chip oscilloscope (OCO) circuit to measure eye diagrams and jitter histograms of high-speed digital signals was presented. A novel architecture to capture both single-ended and differential signals was implemented and it is capable of measuring the eye openings and jitter of the input signals without the need to construct the whole eye diagram which makes it a suitable candidate for eye-opening monitor circuits. In the existing system, an asynchronous sampling technique and an efficient algorithm are employed to decrease the area of the OCO as well as its processing time. That circuit is fabricated in a 65-nm CMOS technology and the measurement results show sub-picosecond resolution when the input signals consist of a 10-GHz clock signal and a 12.5-Gb/s pseudorandom binary sequence. The OCO circuit has a power consumption of 1.9 mW, and its core area is 40 × 60 ?m.
