Buffered direct injection pixel for infrared detector 2015-11-17 · A buffered direct injection pixel is disclosed that includes a photodiode for receiving an input signal, a direct injection transistor associated with the photodiode, and a Sackinger current mirror coupled with the direct injection transistor, providing reduced size, low noise and low power, as compared to prior art buffered direct injection pixels.
Buffered direct injection multiplexer for improved
CMOS readout circuit design for infrared image sensors Schematic of the gate modulation input (GMI) readout cell circuit. The buffered direct injection (BDI) readout cell , as shown in Fig. 5, has lower input resistance and can provide precise biasing voltage to the photodiode compared to the DI readout cell. An amplifier with gain of Av is adopted to provide negative feedback to the gate of the Migrate HTTP handlers and modules to ASP.NET Core
