Abstract
When a time difference is amplified by a time difference amplifier, slew rates of internal output voltages are changed according to a phase combination of digital input signals so that a time gain is determined by a ratio between the slew rates and the slew rates can be controlled from an outside. After a voltage is charged to the level of a power supply voltage in first and second charging capacitors, the charged voltage of the first charging capacitor is decreased with a first slew rate when a first digital input signal transitions, and both charged voltages of the first and second charging capacitors are decreased with a second slew rate when a second digital input signal transitions so that both first and second digital input signals are changed from initial phases, while being compared with a reference voltage to generate first and second digital output signals.
