Abstract
An integrated CMOS amplifier channel consisting of a transimpedance pr eamplifier, postamplifiers, and gain control circuitry has been design ed for the receiver of a pulsed time-of-flight laser radar. The measur ement results, a total transimpedance of Z(t) almost-equal-to 250 kOME GA with a bandwidth of BW almost-equal-to 65 MHz and an input-referred noise current of i(ni) almost-equal-to 7 pA/square-root Hz, show that a range measurement resolution of centimeter/decimeter class could be achieved by detecting the edge of the received laser pulse.
