Title:
LINEAR IMAGE SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/043213
Kind Code:
A1
Abstract:
This linear image sensor is provided with N units 101 to 10N, a readout circuit, and a control unit. Each unit 10n is provided with a photodiode 50 and a source follower amplifier 60. The source follower amplifier 60 includes a MOS transistor 61, an operation control switch 62, and a current source 63. The gate of the MOS transistor 61 is connected to a cathode of the photodiode 50 via a MOS transistor 51. The operation control switch 62 is provided between the source of the MOS transistor 61 and a connecting node 64. The current source 63 is provided between the connecting node 64 and a second reference potential input terminal. In this way a linear image sensor capable of suppressing power consumption can be realized.
