InGaAs linear image sensors
G9211 to G9214 series G9205 to G9208 series
Near infrared image sensors (0.9 to 1.67 μm / 2.55 μm)
The G9211 to G9214/G9205 to G9208 series InGaAs linear image sensors are specifically designed for near infrared multichannel spectrophotometry. These linear image sensors consist of an InGaAs photodiode array, a charge amplifier array, an offset compensation circuit, a shift register and a timing generator formed on a CMOS chip. The charge amplifier array is made up of CMOS transistors connected to each pixel of the InGaAs photodiode array. Signals from each pixel are read out in charge integration mode to achieve high sensitivity and stable operation in the near infrared spectral range. The package is hermetically sealed for high reliability. Signal processing circuits on the CMOS chip can be selected from two conversion efficiencies (CE) by external voltage. The image sensor operates over a wide dynamic range when CE=16 nV/e- and delivers high gain when CE=320 nV/e-.

*1: A major source of noise in charge amplifiers is the reset noise generated when the integration capacitance is reset. A CDS (correlated double sampling) circuit greatly reduces this reset noise by holding the signal immediately after reset to find the noise differential. *2: Different signal timings must be properly set in order to operate a shift register. In conventional image sensor operation, external PLDs (programmable logic device) are used to input the required timing signals. However, the G9211 to G9214/G9205 to G9208 series image sensors internally generate all timing signals on the CMOS chip just by supplying CLK and RESET pulses. This makes it simple to set the timings.
