Abstract :
In analog circuits, power consumption is fundamentally related to noise and the signal bandwidth. In this paper, the theoretical minimum and practical power consumption of various implementations of analog circuits is analyzed. Continuous-time and discrete-time implementations of analog circuits are contrasted. Recent circuit approaches such as comparator and zero-crossing-based circuits are also considered. Finally, the effects of scaling on the power consumption are discussed.
