Method for reusing resource for designing operational amplifier, layout generating apparatus, and layout generating program

摘要

Three kinds of shrink factors, 1 time, 0.5 time, and 0.25 time, are prepared and three sets of operational amplifier layout information are also prepared as a library in correspondence with the three kinds of shrink factors. At each shrink factor, the bias voltage is varied between upper and lower limits to vary the bias current.
