title = "Readout on the resonant-cavity-enhanced InGaAs/GaAs quantum-dot photodetector",
abstract = "Focused on high sensitivity property of the resonant-cavity-enhanced InGaAs/GaAs quantum dots photodetector, the wide dynamic range readout was demanded and designed. The Capacitive Trans-Impedance Amplifier (CTIA) readout structure having bias stability and good linearity compared the characteristic of the Self-Integrated (SI) readout structures is more suitable for the quantum dots photodetector. However, the CTIA structure needs to expand readout dynamic range for effective photoelectric conversion signal output of the novel photodetector. Through the different integration capacitor readout experimental comparison and analysis, a readout structure whose low noise amplification gain could be automatically adjusted was designed, the output dynamic range extended to over 90dB, and the signal to noise and sensitivity of the output signal have been significantly improved.",
