摘要： PROBLEM TO BE SOLVED: To provide a location detection system which can easily and accurately detect a location of a portable device even when effective reception areas of the portable device for a plurality of base stations overlap each other.SOLUTION: A location detection system comprises base stations A1 and A2, and a portable device. Effective reception areas Zone A1 and Zone A2 of the portable device for the base stations A1 and A2 overlap each other at a boundary area Zone C. A base station (dummy transmission antenna) D is provided in the boundary area Zone C. The base stations A1 and A2 periodically transmit signals having different codes at different timing. When the portable device receives signals transmitted from the base station D in one period, the portable device does not reply even if the device receives signals transmitted from the base station in the one period. Thereby, a non-response area Zone D including the boundary area Zone C is formed, and separated actual effective reception areas Zone A1' and Zone A2' are formed.

摘要： PROBLEM TO BE SOLVED: To provide a position detection system capable of detecting the position of a portable machine simply and clearly even if the effective reception areas of a portable machine relative to plural base stations are overlapped.SOLUTION: A position detection system includes base stations A1 and A2, and a portable machine. Effective reception areas Zone A1 and Zone A2 of the portable machine are overlapped in a border area Zone C. A base station (dummy transmission antenna) D is disposed in the border area Zone C. Signals with different codes are simultaneously transmitted from the base stations A1, A2 and D. When a signal from the base station D is received, and when the signals from the base stations A1 and A2 cannot be received separately from the signal from the dummy transmission antenna due to a difference in electromagnetic field strengths between the signals, the portable machine responds nothing. This configuration forms a non-response area Zone E that includes the border area Zone C, and separated effective reception areas Zone A1' and Zone A2'.

摘要： PURPOSE:To simplify the titled circuit by decreasing the area of the source and drain of an NMOSFET to 1/K of the area of the source and drain of a PMOSFET to compensate an offset voltage with high accuracy. CONSTITUTION:N channel FETQ1, Q3 and P channel FETQ2, Q4 are provided and the area of the drain and source of Q1-Q4 is decided so that the drain bulk capacitance and the source bulk capacitance of the Q1, Q3 are made substantially identical with those of the Q2, Q4. In this case, the surface area of the source and drain region of the Q1, Q3 is decided to 1/K times that of the source and drain region of the Q2, Q4. As a result, the total amount of electric charge generated based on the parasitic capacitance of the Q2 and the total quantity of electric charge for correction generated by the capacitance of the Q3 are made equal and no offset voltage compensation circuit is required.
