G8160 to G8163/G8180 series InGaAs linear image sensors are specifically designed for near infrared multichannel spectrophotometr y. 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 allow selecting a feedback capacitance (Cf) of 10 pF or 0.5 pF by using an external voltage input.
The image sensor operates over a wide dynamic range when Cf=10 pF and delivers high gain when Cf=0.5 pF.

*1: CDS (Correlated Double Sampling) circuit
A major source of noise in charge amplifiers is the reset noise gen-
erated when the integration capacitance is reset. A CDS circuit greatly
reduces this reset noise by holding the signal immediately after re-
set to find the noise differential.
*2: Timing generator
Different signal timings must be properly set in order to operate a
shift register. In conventional image sensor operation, external PLDs
(Programmable Logic Devices) are used to input the required timing
signals. However, G8160 to G8163/G8180 ser ies image sensors
internally generate all timing signals on the CMOS chip just by sup-
plying CLK and RESET pulses. This makes it simple to set the tim-
ings.
