METHOD AND DEVICE FOR REDUCING INFLUENCE OF EARELY EFFECT

摘要

PROBLEM TO BE SOLVED: To provide a method for improving the performance of a circuit provided with a three-terminal device.;SOLUTION: In the operation of the circuit provided with a three-terminal device 10, the influence of the Early effect related to the three-terminal device such as FET, for example, is reduced. For reducing such effect, a control part 30 is provided for reducing an Early effect component caused by the three- terminal device. Thus, by controlling the potential of the second terminal (drain, for example), of the device in response to a first signal related to the input signal received by the first terminal (gate, for example), of the device, a potential difference between the second terminal (drain) and the third terminal (source, for example), of the device is practically fixed.;COPYRIGHT: (C)2003,JPO
