  • COMPARATOR CIRCUIT AND ANALOG TO DIGITAL CONVERTER
    Publication number: 20200204188
    Abstract: A comparator circuit is applied to comparing an input voltage and a reference voltage to generate a comparison result. The comparator circuit includes a resistor circuit, a current source circuit and a transistor switching circuit. The resistor circuit receives first and second input voltages in the input voltage. The current source circuit provides a first current and a second current, and the first current, the second current and the resistor circuit generate the reference voltage. The transistor switching circuit generates the comparison result at its output end according to a first control voltage and a second control voltage at its input end. The current source circuit and the resistor circuit generate the first control voltage according to the first current and the first input voltage, and generate the second control voltage according to the second current and the second input voltage.
