Application of a multivariable optimiser to the design of CMOS buffers
Paul R. Routley, Arthur Brunnschweiler, P. Ashburn · Electronics Letters · 1993
A multivariable optimiser is used to individually optimise the size of each stage in a CMOS buffer. When the optimiser is used to minimise the silicon area for a given buffer delay, an area saving of up to 50% is obtained, compared to other types of buffer.
