Integrated circuit with a differential amplifier |
摘要 |
An integrated circuit has a differential amplifier in a basic circuit having two input transistors, a load element and a power source. The power source has an N-type channel MOS transistor whose controlled path is connected to the input transistors and to a supply terminal of the power source. A control terminal of the transistor is connected to a potential that is positive with respect to a reference potential. The supply terminal of the power source is connected to a potential which is negative with respect to the reference potential and which is made available by a voltage source for switching off cell field transistors of a DRAM memory. The gate-source voltage that is increased in this way improves the behavior of the circuit with respect to fluctuations in potential and permits more favorable dimensioning of the transistor.
