Abstract :
In this communication an approach for analyzing and designing low-power CMOS output stages is proposed. The optimization is carried out by taking into account output stage performance parameters which also affect main characteristics of the overall amplifier. To this aim, three quality factors are defined to afford the designer a better understanding of the relationships between current dissipation, area consumption, bandwidth and linearity.
