A buffer design for an integrated circuit that has adjustable slew rate control, yet requires significantly less space to fabricate than does a conventional buffer with slew rate control. A new slew rate control circuit design is added to a Complementary Metal Oxide Semiconductor CMOS buffer to implement slew rate control in the buffer (e.g., selection between a high slew rate and a low slew rate). The new slew rate control circuit requires significantly less space to fabricate, and when applied to each buffer in an given integrated circuit, e.g., input/output buffers that may be placed along the periphery of the integrated circuit, the savings can be extraordinary.
