Abstract
A clock pulse generator includes an input terminal, an input bias setting circuit, first and second pulse shaping circuit and a pulse combining circuit. The input terminal receives a sinusoidal signal. The input bias setting circuit generates an addition sinusoidal signal having a predetermined bias voltage as a central voltage level thereof. The first and second shaping circuits are connected to the input bias setting circuit. The first shaping circuit has a first threshold voltage that is higher than the predetermined voltage and is responsive to the addition sinusoidal signal to generate a first pulse signal. The second shaping circuit has a second threshold voltage that is lower than the predetermined voltage and is responsive to the addition sinusoidal signal to generate a second pulse signal. The pulse combining circuit synchronizes either of the rising edge or the falling edge of the first pulse signal with that of the second pulse signal so as to generate an output clock pulse.
