Abstract
A comparator includes a first voltage-time conversion circuit, a second voltage-time conversion circuit, and a determination circuit. A first delay unit includes a first primary conductivity type transistor of which current is controlled based on a first input signal, a first secondary conductivity type transistor of which current is controlled based on a second input signal, and a first delay buffer provided between the transistors. A second delay unit includes a second primary conductivity type transistor of which current is controlled based on a second input signal, a second secondary conductivity type transistor of which current is controlled based on a first input signal, and a second delay buffer provided between the transistors.
