Abstract
Disclosed is a logic integrated circuit for which the time of switching over between two logic states, 0 and 1, is adjustable. In a logic operator such as an inverter, the switch-over time, at the output, is a function of the current put through by the load transistor or by the signal transistor. This time is adjustable, either as rising time or as fall time, by the replacement of at least one single-drain transistor by a multiple-drain transistor, the throughput rate of which is fixed by the number of connected drains. The disclosed device can be applied to pre-diffused (Si) circuits or pre-implanted (GaAs) circuits.
