ABSTRACT:
A coupled ring oscillator includes n ring oscillators (20) each including m inverter circuits (10), and a phase-coupling loop (40) in which m×n phase-coupling circuits (30), each of which couples signal phases at two points in a certain phase mode, are connected with each other to form a loop. Connection points at which the inverter circuits (10) are connected with each other and the connection points at which the phase-coupling circuits (30) are connected with each other are connected bijectively; and each of the inverter circuits (10) is connected between two points that divide the phase-coupling circuits (30) into two parts at a certain ratio.
