Integrated circuit with programmable speed/power adjustment

摘要

A programmable integrated circuit with adjustable speed/power characteristics having a primary current path which draws a predetermined amount of current; a plurality of impedance elements which generate a reference voltage which controls the current in the current path. One of a plurality of programmable switches is coupled in series, respectively, with one of the plurality of impedance elements, whereby each of the impedance elements can be connected or disconnected by setting its respective programmable switch, thereby adjusting the operating speed and the power consumption of the integrated circuit according to predetermined requirements. The programmable switches used in this invention preferably are erasable, programmable read-only memories.
