The injection efficiency of an 8- to 14-μm hybrid IR/CCD FPA is calculated from a transcendental equation involving the detector, CCD input currents, and the detector impedance Rd at the operating point. The latter has been varied either by changing the composition of x in the Hg1-x Cdx Te detector or by changing the tunneling current while x is kept constant. Calculations were carried out for both weak and strong inversion cases of the input MOSFET of the CCD. It is argued that for the 8- to 14-μm region, since the detector currents are high, operation of the input of the CCD in the strong inversion regime seems more reasonable.
