Wa. Serdijn et al., DESIGN PRINCIPLES FOR LOW-VOLTAGE LOW-POWER ANALOG INTEGRATED-CIRCUITS, Analog integrated circuits and signal processing, 8(1), 1995, pp. 115-120
In this paper it is argued that there are good reasons to choose curre
nt as the information-carrying quantity in the case of low-voltage low
-power design constraints. This paper focuses on the influence of the
transfer quality on that choice. To obtain power-efficient transfer qu
ality, indirect feedback is shown to be a good alternative to traditio
nal feedback techniques.
