Filed: 1987-11-24
Abstract: PURPOSE:To obtain a voltage limiter, which operates at high speed even when outer voltage (Vcc) is equal to output voltage from the voltage limiter and has low power consumption, by inserting a level shift circuit into an input terminal for a differential amplifier and forming source coupling paired transistors for the differential amplifier into N channel transistors. CONSTITUTION:A level shift circuit is inserted to an input terminal for a differential amplifier, and voltage lower than input voltage only by the threshold voltage section of a transistor or voltage lower than said voltage is applied to the input terminal for the differential amplifier. That is, the level shift circuit composed of MOS transistors QL1, QL3 and MOS transistors QL2, QL4 is inserted to the input terminal for the differential amplifier for a limiter. Fixed voltage VG is applied to gates in MOS transistors QL8, QL4, and the transistors QL8, QL4 operate as constant current sources. Consequently, constant currents are made to flow through the MOS transistors QL1, QL2 regardless of the gate voltage of the transistors QL1, QL2. Accordingly, since large currents can be made to flow through the differential amplifier for a voltage limiter circuit even when supply voltage is equalized to input voltage to the differential amplifier, supply voltage drops, and the voltage limiter is operated at high speed even when supply voltage is made the same as output voltage from the voltage limiter.

Subsequently, in the circuit 4, the center value of the input signal and the center value of an input span of the circuit 3 are compared, and when there is a difference, a value for negating its difference and a value given to the circuit 5 at present are outputted to the circuit 5. Also, in the circuit 4, a value from the circuit 4 is outputted to the circuit 2, and by negating the difference between the center value of the input signal and the center value of the input span of the circuit 3, a signal containing no offset is inputted to the circuit 3. Therefore, even when the center value of the input signal is moved due to expansion and creep of a sample, the amplitude can be measured with high accuracy.
