摘要： A photosensor circuit comprises a photoelectric transducer, an n-channel MOS transistor and an initial setting unit for precluding the occurrence of a residual image phenomenon. When an optical signal is generated by the photoelectric transducer, the initial setting unit sets the gate voltage of the n-channel MOS transistor at a high value for a predetermined time to lower the drain-source impedance of the n-channel MOS transistor to thereby control charge or discharge of a capacitor connected to a source terminal.

摘要： A semiconductor sensor includes a field-effect transistor for detecting a physical quantity such as pressure, strain, acceleration or the like. The field-effect transistor is disposed on an elastically deformable portion of a cantilevered semiconductor substrate. A detected signal generator generates a signal representing a change in a drain current of the field-effect transistor in response to a stress which is applied to the field-effect transistor due to elastic deformation of the semiconductor substrate. The field-effect transistor may be supplied with a fixed gate bias voltage and an integrator may generate a signal representing an integral of the drain current for temperature compensation. Alternatively, an integrator may generate a signal representing an integral of the drain current, and a gate bias voltage may be applied to the field-effect transistor so that the signal generated by the integrator will be of a predetermined value for automatic temperature compensation. As a further alternative, a self-bias circuit may be connected between the field-effect transistor and the detected signal generator for applying a gate self-bias voltage to the field-effect transistor for automatic temperature compensation.

摘要： This invention relates to a semiconductor sensor for detecting external physical forces, such as acceleration, contact pressures, air pressures, mechanical vibrations, etc. The semiconductor sensor according to this invention is characterized by the use of compound semiconductors of high piezoelectricity, such as GaAs, etc. Conventionally sensors of the cantilever type, diaphragm type, etc. are made of silicon. These prior art sensors have low detection sensitivity, and their characteristics tend to deteriorate. The sensor according to this invention is made of GaAs, which has high piezoelectricity and can retain good characteristics of the semiconductor even at high temperatures and includes a field-effect transistor formed on the GaAs for sensing a stress. The FET is driven by a constant current or a constant voltage so as to detect a change of an electrical characteristic (e.g., threshold characteristic) due to a stress. The structure of the sensor according to this invention enables the sizes of the sensors not only to be diminished but also to reduce the fabrication costs. When a stress is applied to the FET, the transconductance changes, and the temperature changes, consequently the I-V characteristic changes. An a.c. signal biased by a direct current is supplied to the gate of the FET, and a drain current is detected in an a.c. component and a d.c. component so as to detect a temperature concurrently with a detection of a stress.

摘要： An output compensating device capable of optimally compensating output signals of an image sensor composed of a number of light-sensor circuits, each of which represents a unit pixel and is capable of producing in a photoelectric converting element a sensor current proportional to a quantity of light falling thereon, converting the current into a voltage signal by a MOS type transistor with a logarithmic output characteristic in a weak inverse state, initializing itself by removing a charge accumulated in a parasitic capacitor of the photoelectric converting element by changing a drain voltage of the transistor to a value lower than a normal value for a specified time and outputting a pixel signal having a logarithmic characteristic at a large quantity of the sensor current and a pixel signal having a non-logarithmic characteristic at a small quantity of the sensor current. This device has a means for compensating each pixel signal from the image sensor for an offset value and outputting a resulting signal if said signal has an output characteristic within a logarithmic response region or a non-logarithmic region depending on the output condition and, if not, further compensating the offset-compensated signal for its gain and outputting a resulting signal, thus ensuring the optimal compensation of each pixel signal of the image sensor in accordance with its output state.
