In this paper for the first time a butterfly inspired optimization algorithm, both in single- and multi-objective version is adapted for analog circuit design. As design examples a two-stage amplifier and a current conveyor are respectively used as a voltage and current mode circuits. For the amplifier, the effects of pole-zero compensation on the stabilization performance is first investigated and then, the proposed approach is used for its optimal sizing. Higher dc gain, larger bandwidth and phase margin are then ensured by this way. For the current conveyor, the effect of channel length and bias current on its main performances is considered. The proposed optimization algorithm allows for a high cut-off frequency and small occupation area. Compared to what previously published, the proposed approach provides better figures of merit for both circuits and can be helpful for the optimal sizing of integrated analog circuits, to meet the challenge of automated design in Very-Large-Scale Integration microelectronic domain.

本文首次将单目标和多目标版本的蝶型优化算法用于模拟电路设计。作为设计实例，两级放大器和电流传送器分别用作电压和电流模式电路。对于放大器，首先研究零极点补偿对稳定性能的影响，然后将所提出的方法用于其最佳尺寸。这样就可以确保更高的直流增益，更大的带宽和相位裕度。对于当前的输送机，要考虑通道长度和偏置电流对其主要性能的影响。所提出的优化算法允许高截止频率和较小的占用面积。与以前发布的相比，
