Tunable Spectral Responses in a Color-Sensitive CMOS Pixel for Imaging Applications

  title={Tunable Spectral Responses in a Color-Sensitive CMOS Pixel for Imaging Applications},
  author={Giacomo Langfelder and Federico Zaraga and Antonio Francesco Longoni},
  journal={IEEE Transactions on Electron Devices},
The transverse field detector (TFD), a recently proposed type of CMOS color-sensitive pixel for imaging applications, has an intrinsic and peculiar characteristic of tunable spectral response. The TFD color-detection principle relies on the generation of a suitable electric field configuration in a depleted region of a CMOS low-doped silicon active layer. Depending on the applied voltage at the biasing/collecting electrodes, different electric field configurations can be obtained. In the… CONTINUE READING
