Title: Contact type image sensor
Inventor: MATSUYAMA TOSHIRO
IPC: H04N5/335
Filed: 1987-04-06
Abstract: PURPOSE:To have both high photosensitivity and the facility of signal processing, by composing a means for electrically scanning a photodetector of a means in which voltages are applied sequentially to a transparent electrode, and further by composing a photoelectric conversion film of an amorphous silicon film. CONSTITUTION:A polycrystal silicon thin film 2 is formed on a glass substrate 1, and (n) or (p) regions are formed thereon as source and drain regions 3, 4. A photoelectric conversion film 7 is formed on a gate electrode 6 so that the gate electrode 6 is structured to also serve as a lower electrode of the photoelectric conversion film 7. When a voltage is applied to a transparent electrode 8, light is made incident to the photoelectric conversion film 7. When a resistance is low at that time, the gate electrode 6 becomes equipotential to the transparent electrode 8 and so a gate voltage VG is equivalently applied to the gate electrode 6, so that FET is turned on to make a current flow between the source and drain. A large signal current can be hence obtained and a signal source impedance can be lowered and also S/N ratio drop due to parasitic capacity can be suppressed accordingly.

IPC: H03G3/12
Filed: 1983-05-13
Abstract: PURPOSE:To prevent a latch-up phenomenon with a simple circuit constitution by supplying the output of a differential amplifier whose working current is controlled by an input level to a current inverting circuit and controlling the output current of the current inverting circuit with a current limiting element. CONSTITUTION:The signal which is supplied to a terminal 6 and is subjected to level control is applied to a differential amplifier 2, and the output of the amplifier 2 is rectified 12 and smoothed 16 to be supplied to a transistor (TR)20. Thus the working current flowing through the TR20 is controlled in response to the input level. The working current of a differential amplifier 18 is decided by the current of the TR20. The current flowing through TRs22 and 24 is detected by the TRs32 and 36 of current inverting circuits 30 and 34 and applied to the TRs 38 and 40. The currents flowing through the TRs38 and 40 are synthesized by a current inverting circuit 44. The shortage of the suck-in and suck-out currents flowing through the TRs38 and 48 is controlled by the input signal sent from the terminal 6. As a result, the level of input signal is controlled by the output level of the amplifier 2 and extracted through an output terminal 10. When the current of the TR38 has an abnormal increment, the sudden increment of current is suppressed by the voltage drop of a current limiting element 42.
