Abstract
Official abstract text for this publication.
A cross-coupled oscillator arrangement has a first resistance-capacitance oscillator core including at least two inverting stages; and a second resistance-capacitance oscillator core substantially identical to the first resistance-capacitance oscillator core. The first oscillator core and second oscillator core are cross coupled in anti-phase using coupling capacitors. The first oscillator core and second oscillator core are also connected in series such that the first oscillator core is supplied with a supply between a first potential and a second potential and the second oscillator core is supplied with a supply between the second potential and a third potential.
