Abstract: A control voltage generator and a related method generate control voltages having a phase difference. The control voltage generator includes first thru N-th loads (where N is a positive integer no less than 2), and is installed in an electronic device that may experience noise or malfunction when signals having the same phase are simultaneously inputted into the loads. In the control voltage generator, a sawtooth generator generates and outputs a sawtooth signal. and a first driving signal generator compares the sawtooth signal generated by the sawtooth generator with an input signal having information as to the degree of variation of an inherent level, which relates to an inherent function of the electronic device. The comparison result is outputted as a first driving signal. The control voltage generator also includes second thru N-th driving signal generators. An n-th driving signal generator (where 2
