PROCESS COMPENSATED INTEGRATED CIRCUIT OUTPUT DRIVER |
摘要 |
An integrated circuit output driver which reduces the effect of power supply and/or integrated circuit fabrication process variations on signal propagation delay. The output driver produces an output signal V out as an increased drive strength replica of an input signal V in. A pre-driver receives V in and produces an intermediate, inverted replica V int thereof. A driver is electrically connected to the pre-driver's output to receive V int. V out appears at the driver's output as an inverted, strengthened replica of V int. A first feedback circuit electrically connected between the driver's input and output applies a pull-down signal to the driver's input in response to a falling edge of V in, with the pull-down signal's strength varying in inverse proportion to propagation delay of the falling edge of V in. A second feedback circuit electrically connected between the driver's input and output applies a pull-up signal to the driver's input in response to a rising edge of V in, with the pull-up signal's varying in inverse proportion to propagation delay of the rising edge of V in.
