Abstract :
A new input circuit, called the current mirroring direct injection (CMDI) circuit, is proposed for infra-red detector readouts. This new input circuit leads to almost 100% injection efficiency even in the case of low diode dynamic resistance. In addition, it can provide a stable detector bias and can be implemented with a small unit cell area and low power consumption
