Abstract

In this paper a systematic design approach based on noise optimization with power consumption minimization for operational transconductance amplifiers OTAs is presented In this methodology HSPICE and ant colony optimization ACO algorithm are used as simulation tool and optimization method respectively By rewriting the thermal noise flicker noise corner frequency and other specifications of the OTA based on the Gm/Id characteristic in all regions of transistor operation noise optimization beside the power minimization is achieved in a reasonable simulation time In this approach ACO is applied in order to optimize the design variables aim at minimizing the input referred noise and power consumption The design methodology is successfully used for systematic design and optimization of a CMOS Miller folded cascade amplifier using 018 µm CMOS technology in the three regions of amplifier operation Simulation results confirm the accuracy of the theoretical analysis in the presented design methodologyWe declare that this manuscript is original has not been published before and is not currently being considered for publication elsewhere We confirm that the manuscript has been read and approved by all named authors and that there are no other persons who satisfied the criteria for authorship but are not listed We further confirm that the order of authors listed in the manuscript has been approved by all of us We understand that the corresponding author is the sole contact for the Editorial process He/she is responsible for communicating with the other authors about progress submissions of revisions and final approval of proofs
