Abstract :
An integrated CMOS differential amplifier channel consisting of a transimpedance preamplifier, postamplifiers and gain control circuitry has been designed for the receiver of a pulsed time-of-flight laser range finding device. The amplifier channel has a measured total transimpedance of Zt≈1.27 MΩ with a bandwidth of BW≈60 MHz and an input-referred noise current of ini≈4.5 pA/√(Hz)
