Readout ASIC for IR imaging detectors and cameras

Readout ASIC for IR imaging detectors and cameras

Gated Imaging systems use a gated imaging sensor and a VCSEL (Vertical-Cavity Surface-Emitting Laser) to generate a clear image and to generate range maps. This readout ASIC is connected with the IR (InfraRed) image detector using flip-chip technology.

Features

  • Application: imaging through smoke, haze, fog and dust
  • Gated imaging principle (<50 nsec), frame rate 150FPS
  • Available pixel area on chip <500um2
    • Image detector sensor connected to ROIC (ReadOut IC) using flip-chip technology
    • Ultra-low-noise design
    • Capacitive transimpedance amplifier and Correlated-Double-Sampling
 integrator stage
    • Analog output buffer
  • Digital sequencer
    • Integration window based on laser input and application
    • Read-out sequence (column / row)
    • SPI interface for configuration and test
  • 0.18um process technology
