A fast and accurate method of redesigning analog subcircuits for technology scaling

Seiji Funaba; Akihiro Kitagawa; Toshiro Tsukada; Goichi Yokomizo

In this paper, we present an efficient approach for technology scaling of MOS analog circuits by using circuit optimization techniques. Our new method is based on matching equivalent circuit parameters between a previously designed circuit and the circuit undergoing redesign. This method has been applied to an MOS operational amplifier. We were able to produce a redesigned circuit with almost the same performance in under 4 hours, making this method 5 times more efficient than conventional methods.
