Portable Time Interval Counter with Picosecond Precision
نویسندگان
چکیده
This paper presents the design, architecture, and operation of a precision time interval and frequency counter made as a small, portable instrument with USB interface. Thanks to the use of advanced time interpolators designed in a CMOS chip, the precision (standard deviation) below 35 ps was obtained at measured time interval from 0 to 200 ms. The frequency can be measured up to 3.5 GHz. The dedicated control software creates a user-friendly and versatile graphic interface in Windows environment. Key-Words: time interval counter, time digitizer, time-to-digital converter, time interpolation, two-stage interpolation

Traditionally, electrical discharge machining (EDM) or conventional laser tools have been used to manufacture a range of precision medical devices. However, these manufacturing methods cannot be used to achieve the miniature features, precision, surface quality, and yields required for manufacturing microfluidic devices for clinical lab-on-a-chip applications, precision drug-delivery catheters,...
متن کاملVernier ring based pre-bond through silicon vias test in 3D ICs
Defects in TSV will lead to variations in the propagation delay of the net connected to the faulty TSV. A non-invasive Vernier Ring based method for TSV pre-bond testing is proposed to detect resistive open and leakage faults. TSVs are used as capacitive loads of their driving gates, then time interval compared with the fault-free TSVs will be detected. The time interval can be detected with pi...

Sub-picosecond optical pulses have been successfully generated using a novel monolithic passive colliding pulse mode-locked (CPM)l semiconductor multiple quantum-well (MQW) laser. Transform-limited pulse width of 830 femto-seconds is achieved at a wavelength of 1.5pm and a repetition rate of 80 GHz. The measured timebandwidth product is 0.31. A record high repetition rate of 350 GHz is also dem...
