Abstract
A time integrator integrates time axis information represented by a phase difference between two signals. The time integrator includes a pulse generation circuit configured to convert a time difference between edges of two input signals to a difference between pulse widths of two pulse signals, and to output the two pulse signals, a load circuit having load characteristics changed by the two pulse signals, and an oscillation circuit coupled to the load circuit, and having an oscillation frequency changing in accordance with the load characteristics of the load circuit. An output of the oscillation circuit is output as a result of time integration.
