摘要： A second source follower circuit of a reference voltage generator includes a transistor having the same characteristics as a first source follower circuit of a pixel. Accordingly, the second source follower circuit can generate a second reference voltage according to the change in characteristics of the first source follower circuit. A noise voltage switching circuit outputs a first voltage as a noise voltage to a pixel signal generator when the noise voltage is equal to or lower than the second reference voltage. In a reset state, the noise voltage and the second reference voltage always have a predetermined voltage difference. Therefore, deterioration in image quality can be prevented even when capturing a subject having high brightness. Since a trimming circuit or the like selecting any one of a plurality of reference voltages according to characteristics of a formed transistor becomes unnecessary, the cost of an imaging device can be reduced.

摘要： A differential amplifier has a first input terminal to which a voltage of a noise signal of the solid-state imaging device is supplied and a second input terminal to which a voltage of a temporary data signal having the noise signal of the solid-state imaging device superposed thereon is supplied. The differential amplifier inverts an output signal when a magnitude relationship in voltage between the first and second input terminals becomes reverse. A measurement circuit measures a variation amount of a voltage of the second input terminal from when the voltage of the second input terminal begins to vary in a direction to reverse the magnitude relationship to when the output signal of the differential amplifier is inverted, and outputs a measurement result as a digital value indicating a voltage of a real data signal obtained by removing the noise signal from the temporary data signal.

摘要翻译： 参考电压发生器的第二源极跟随器电路包括具有与像素的第一源极跟随器电路相同的特性的晶体管。 因此，第二源极跟随器电路可以根据第一源极跟随器电路的特性的变化产生第二参考电压。 当噪声电压等于或低于第二参考电压时，噪声电压切换电路将作为噪声电压的第一电压输出到像素信号发生器。 在复位状态下，噪声电压和第二参考电压总是具有预定的电压差。 因此，即使在拍摄具有高亮度的被摄体的情况下也能够防止图像质量的劣化。 由于不需要根据形成的晶体管的特性选择多个参考电压中的任何一个的微调电路等，因此可以降低成像装置的成本。
