Abstract
A readout circuit which may be in the form of a readout integrated circuit or ROIC is disclosed for use in an AM chirp LADAR system having a photodetector coupled to a passive electronic filter. The filter output is coupled to a capacitive-coupled transimpedance amplifier with an output coupled to an analog storage register. The analog storage register output is coupled to a sample-and-hold circuit which in turn is coupled to an analog to digital converter circuit. In the stacked configuration, each IC operates independently and outputs its signals on a unique output line. The stacked ICs operate under the same set of control vectors as the individual ICs comprising the stack.
