Abstract
The invention provides a comparator and a relaxation oscillator. The comparator comprises a comparator circuit. The comparator circuit comprises a current mode comparator circuit. The current mode comparator circuit comprises a first current mode comparison circuit and a second current mode comparison circuit. Both the first current mode comparison circuit and the second current mode comparison circuit are electrically connected with a first input end and a second input end of the comparator circuit; the first current mode comparison circuit comprises two N-type MOS transistors; gate electrodes of the two N-type MOS transistors are electrically connected with each other; the second current mode comparison circuit comprises two P-type MOS transistors; and gate electrodes of the two P-type MOS transistors are electrically connected with each other. The oscillator comprises the comparator.
