摘要： A semiconductor device for a tuner capable of simultaneously satisfying a low noise factor, low third order distortion characteristics and low power consumption, and a tuner using this semiconductor device for a tuner and capable of reducing the size and eliminating labor during assembly. The semiconductor device is a variable gain amplification circuit comprising a gate grounded circuit using a transistor, and a differential amplification circuit including transistors and constant current sources. Transistors are used as variable resistance devices, and the gain of the gate grounded circuit can be varied by changing the gate voltage of a transistor. The gain of the differential amplification circuit can be varied by changing the gate voltage of another transistor. The overall gain of the circuit can be varied within a necessary range by simultaneously operating these gain controls, and the third order distortion can be improved monotonously with the decrease of the gain.

摘要： A particle size distribution measuring apparatus includes a source of laser light for providing a laser beam to a sample cell that can hold a sample to be measured. A condenser lens converges the laser beam towards the sample cell along an optical axis. The position on the other side of the sample cell is a ring detector unit that can be aligned with the optical axis to measure light intensity at relatively small scattering angles from contact with particles in the sample cell. An array of detectors can be operatively positioned on a substrate with appropriate amplifying multiplying and analog to digital conversion capacity for measuring light intensity at relatively large scatter angles. The outputs of the ring detector unit and the array of detectors can be used to determine the particle size distribution of particles in the sample.

摘要： A gain control circuit includes a first FET for serving as an active load, a second FET serving as an amplifier, and a third FET for serving as a current source. The first, second, and third FETs have substantially the same characteristics and are mutually connected in a series. The gain control circuit further includes a fourth FET for serving as a variable active load connected in parallel with the third FET and a capacitor connected between the third and fourth FETs. The fourth FET is also connected to a gain control terminal. The gain of the second FET is controlled by the voltage applied to the gate of the fourth FET through said gain control line.
