Title: Offset correcting circuit
Inventor: KANBARA SATOSHI
IPC: H03F3/34
Filed: 1988-11-08
Abstract: PURPOSE:To correct the offset without being affected by values of the through rate of a differential amplifier, the output current, the offset correction capacity, etc., by connecting the non-inverted input terminal and the inverted input terminal of the differential amplifier before the sampling period of the offset voltage. CONSTITUTION:Control signal sources 6 and 7 are provided, and the control period of a time series to the input of a differential amplifier 1 is divided into three by a control circuit 2. In the first control period, the non-inverted input terminal, the inverted input terminal, and the output terminal of the differential amplifier 1 are short-circuited. In the second control period, a capacity element connected to the non-inverted input terminal of the differential amplifier 1 is short-circuited to supply a reference voltage and the non-inverted input terminal and the output terminal are short-circuited. In the third control period, an analog signal input source 5 is connected to the capacity element connected to the non-inverted input terminal of the differential amplifier 1 and the output terminal is connected to the capacity element connected to the inverted input terminal. Thus, the offset correction voltage is outputted without being affected by the through rate of the differential amplifier, the output current, the offset correction capacity value, or the input voltage value.

IPC: H04M1/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a radio telephone equipment and a picture display device capable of properly and speedily answering by easily confirming a call originating source at the time of an incoming call. SOLUTION: The face, etc., of a frequent caller is photographed and stored with his/her telephone number in the picture display device 201 connected to the radio telephone equipment 202. Then, in a case when a call incomes to the equipment 202, an originating number is sent to the display 201 to retrieve whether a pertinent telephone number is stored or not and when there is a coincident one, its picture is displayed on the picture display part. Thus, since the picture of the face, etc., of the a caller is displayed with the ringing of an incoming call bell, a callee can visually specify the caller in a short time. In addition, by providing an on-hook/disconnecting switch at the picture display, ringing of the bell is stopped by the picture display device without requiring fetching the radio telephone equipment main body from a bag or a pocket during ringing of the bell.
