Abstract :
A differential BiCMOS linear amplifier channel with gain control and a peak detector have been designed for a pulsed time-of-flight laser radar. The bandwidth of the amplifier channel is ~160 MHz and its gain can be controlled with a variable R-2R ladder attenuator in 7 discrete steps from 0.44 to 23. The peak detector can detect the peak of a single 10 ns pulse, the amplitude of which is varying from 50 mV to 3.5 V
