COMPARATOR CIRCUIT

A comparator circuit is provided, including an input current generation section configured to generate an input current based on an input voltage, a reference current generation section configured to generate a reference current based on a reference voltage, a first current-voltage conversion section configured to convert the input current to a comparison-target voltage, a second current-voltage conversion section configured to convert the reference current to a threshold voltage, and a comparison section configured to compare the comparison-target voltage against the threshold voltage. The input current generation section includes a first transistor having a gate and a drain that are connected together, and the input voltage is input to the drain of the first transistor via a resistor. 一种比较电路，包括：输入电流生成部，基于输入电压生成输入电流；基准电流生成部，基于基准电压生成基准电流；第一电流电压转换部，将输入电流转换为被比较电压；第二电流电压转换部，将基准电流转换为阈值电压；以及比较部，对被比较电压和阈值电压进行比较，输入电流生成部具备栅极和漏极连接并经由电阻向漏极输入输入电压的第一晶体管。
