Abstract :
An integrated time measurement unit for use in portable, low power laser rangefinding devices is described. It is implemented with 1.2 μm CMOS technology and has a measurement range of 10 us and an accuracy of ±0.2 ns over the temperature range 0...60°C and supply voltage range 4.5...5.5 V. Single shot time measurement resolution is ±0.9 ns. Nominal current consumption is 3 mA
