An Approach Towards Design of Analog Integrated Circuits Based on Fixator–Norator Pair

Abstract

This paper presents a novel method for the design of analog integrated circuit, making use of fixator–norator pairs for the performance design and biasing design. Fixators are the distinctive tools for setting a critical design parameter at a desired value whereas the pairing norator renders these critical parameters into adequate supporting components, mainly resistors. For analog ICs, active loads and current mirrors serve as supporting components. Hence, the use of fixator–norator pairs may abbreviate as defining the dynamic and static resistance of active loads and current mirrors that should be affirmative with a given design. The proposed methodology is illustrated by the use of a common emitter amplifier, a BJT differential amplifier, a MOS operational amplifier and a three-stage CMOS operational amplifier.
