    摘要: An analog accumulator used in association with a solid state image analyzer for averaging and storing the fixed pattern noise (FPN) includes an N-stage transfer shift register with an input receiving a signal corresponding to the fixed pattern noise and with N outputs, N floating storage diodes each connected to an output of the transfer shift register, N reading parts each connected to a floating storage diode and each comprising a floating input diode connected to the floating storage diode through an injection gate, an injection device and a charge removal drain, and an N-stage transfer shift register with N inputs each connected to a reading part and with an output. The accumulator provides M integrations of N samples of an analog signal and delivers, at the end of the M integrations, the N accumulated samples several times.
