OSCILLATION CIRCUIT AND SEMICONDUCTOR INTEGRATED CIRCUIT INCLUDING THE SAME

An oscillation circuit including, a latch for generating an output signal based on a first signal and a second signal, an electric-charge charge/discharge unit which has first and second capacitors, and charges or discharges the first and second capacitors complementarily based on the output signal, a first comparator which compares a first voltage according to electric charge accumulated in the first capacitor and a first reference voltage, and outputs the first signal, a second comparator which compares a second voltage according to electric charge accumulated in the second capacitor and the first reference voltage, and outputs the second signal, and a control unit for controlling a timing, to compensate for variations of signals in the latch, the first comparator, and the second comparator, at which respective voltage levels of the first reference voltage and the first voltage match.
