Abstract
An integrated receiver that includes both the time-to-
digital converter (TDC) and the receiver channel and is intended
for a pulsed time-of-flight laser rangefinder with a measurement
range of approximately 10 m has been designed and fabricated in
a standard 0.13
m CMOS process. The receiver operates by de-
tecting the current pulse of an optical detector and producing a
stop timing mark for the TDC by means of a leading edge timing
discriminator. The TDC is used to measure the actual time interv
