A 9x9 Single-Photon Avalanche Photodiode (SPAD) array with a 10-channel time-to-digital converter and an integrated laser diode driver fabricated in 0.35 μm HV- CMOS technology were used to [...]
An integrated receiver-TDC (time-to-digital converter) chip set is developed for pulsed time-of-flight (TOF) laser rangefinding. The receiver detects the current pulse from the optical [...]
A laser rangefinder device based on pulsed time-of-flight (TOF) distance measurement techniques was constructed and tested. Key blocks of the system are the integrated receiver channel and the [...]
A time-to-digital converter (TDC) often consists of sophisticated, multilevel, sub-gate delay structures, when time intervals need to be measured precisely. The resolution improvement is [...]
This paper presents the design of a CMOS time-to-digital converter (TDC) used in a direct time-of-flight laser radar line receiver consisting of an array of single-photon avalanche diodes [...]
