Title: Operational amplifier circuit
Inventor: YOSHIHARA TOSHIO
IPC: H03F3/30
Filed: 1993-12-01
Abstract: PURPOSE:To reduce the power consumption of the circuit connecting to the post stage of the differential amplifier circuit by providing a limiter function against an excess input signal to an output stage of the differential amplifier circuit. CONSTITUTION:Transistors(TRs) 11 and 14, 12 and 15, 19, and 22 and 23 act like constant current sources respectively under respective bias voltages. When an excess input voltage is received to an input terminal 5 in comparison with an input terminal 6, the TR 21 is conductive, Then a potential of an output terminal 8 at a high level is set to a low level by the conducting state of the TR 23. However, the potential at the output terminal 8 is not decreased below a sum of a drain-source voltage of the TR 21 and a gate-source saturated voltage of the TR 24 with respect to a low level power terminal 10 and then an output is limited. Since an output stage has a limiter function with respect to an excess input signal, a current consumption required for a circuit connected to the post stage is reduced.

Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To measure a shape of an object to be measured with high precision by using convolutional integration as a filtering method for removing a carrier component in a moire fringe. SOLUTION: As an object to be measured is an aspherical shape in a virtual screen data determined by a virtual interference fringe calculator 13, a space frequency of a carrier component has a band width. An interference fringe including a light wave surface data is fetched from a CCD camera 10 as a measured image data and converted into a digital data by a capture board 11. The measured image data fetched into the board 11 and a virtual image data of an initial phase written in a frame memory 14 are multiplied by a multiplier 18. A kind of moire fringe with a low space frequency that means an error shape of the object to be measured and a high carrier with high frequency is generated by this calculation.  If a carrier component is cut off with a convolutional integrator 19 being a filtering function, a sharpened moire fringe with the low space frequency generated by an electronic moire can be obtained.
