Abstract
The performance of different LC oscillator topologies is evaluated, showing that their current and power requirements are fundamentally equivalent for many commonly employed single-stage circuits, and are subject to a practical lower limit dictated by the characteristics of the active devices and inductors used. Two fundamental quality indi- cators are defined, which can summarise their current and energy per- formance. An example of a two-stage circuit is provided, which is not subject to that limit.File in questo prodotto:
