THE I/O OUTPUT BUFFER AUTOMATED DESIGN WITH CONSIDERATION OF SIMULTANEOUSLY SWITCHING NOISES

The sizing rules method for analog CMOS I/O output buffer circuit design that consists of two pre-buffers (inverters) and output inverter is presented. The sizing rules method efficiently captures design knowledge on the technology-specific level of transistor pair groups. This reduces the preparatory modeling effort for I/O circuit design. No expert knowledge about the circuit is required as in most knowledge based optimization tools. 1
