Abstract
A current-controlled oscillator with first and second differential comparators (640, 840) serving as inputs, first and second voltage independent multi-layered integrated capacitors (600, 800) corresponding to the first and second comparators (640, 840), and a RS latch (700) for switching operation between the two comparators (640, 840) thereby achieving oscillation. The multi-layered integrated capacitors (600, 800) are designed to provide voltage independent capacitance.
