Abstract
An improved logic circuit is disclosed, of the type in which one or more input signals, generated by one or more input signal generator circuits, are referenced to a threshold voltage, determined by a threshold voltage generator circuit, to determine whether said one or more input signals are in a high or low state. In this improved logic circuit, the time constants of the input signal generator circuits are matched with those of the threshold voltage generator circuit so that any power supply perturbations commonly applied to the input signal generator circuits and threshold voltage generator circuit, such as due to the switching on or off of output loads, will result in these circuits having substantially identical frequency responses and amplitude versus time responses.
