Abstract
Disclosed is a pre-diffused logic integrated circuit, a part of which is converted into an analog circuit. A pre-diffused logic circuit includes a plurality of logic circuits, each formed by non-wired signal transistors. If the fan-out of a logic operator has to be increased, the transistors of a neighboring logic cell are parallel mounted so that at least two signal transistors are parallel mounted to make an amplifier transistor therefrom and at least two transistors are connected to make a current source therefrom for this amplifier. This conversion is done during the final metallizations for customizing the pre-diffused circuit. The present invention finds particular application in fast logic circuits.
