Abstract
A frequency agile voltage controlled oscillator is provided in which amplitude control is performed by digitally controlling the current supplied to the oscillator from a current source (). The use of digital control means that phase noise performance of the oscillator is not degraded by the introduction of noise from the current source controller.
