ABSTRACT:
An apparatus for diminishing supply and ground bounce in integrated circuits. Two separate techniques are used simultaneously to diminish the problem of ground bounce. First impedance is placed between a power source bus on the integrated circuit and an external power source; and between a ground bus on the chip and an external ground. This effectively dampens ground bounce oscillations in the power and ground leads of the chip. Secondly, capacitance is dynamically added to the pre-drive of an output buffer with a capacitance node. Dynamic digital sizing is utilized in both techniques, therefore both techniques are responsive to the changing performance variations within the chip.
