Abstract

An integrated CMOS 0.35/spl mu/m receiver channel with a wide dynamic range for a pulsed time-of-flight laser rangefinder was designed and tested. The circuit uses a leading edge timing discrimination technique. The measured bandwidth, transimpedance and an input referred noise current are 80 MHz, 122 k/spl Omega/ and 6.1 pA//spl radic/Hz. The measured walk error is 0.6 ns in 1:1000 dynamic range. The time-to-digital converter (TDC) is also implemented on the same chip.
