Paper Abstract

In this paper, we propose a new unit cell, named current mirroring direct injection (CMDI) circuit for focal plane arrays. With the current mirroring effect, the circuit designed to control detector bias automatically. Its characteristics are derived analytically, and compared with those of direct injection (DI) and buffered direct injection (BDI). With the CMDI approach, we can achieve almost zero input impedance. Therefore, almost 100% injection efficiency can be obtained even for low RDA values. It has also other advantages such as near zero detector bias, relatively small area and low power consumption.
