Abstract
A small area oscillator circuit is provided. The oscillator circuit includes first and second constant current sources, a comparator, first and second capacitive elements, and a resistive element. In a first state, the first capacitive element is connected to the first constant current source and the fixed voltage node, the second capacitive element is connected to the second constant current source and the first current source, and resistive element is connected to the second constant current source. In a second state, the first capacitive element is connected to the second constant current source and first constant current source, the second capacitive element is connected to the second constant current source and the fixed voltage node, and the resistive element is connected to the first constant current source.
