ABSTRACT:
A voltage divider for dividing an input voltage includes a fixed resistor, a variable resistor, an input node and an output node. The fixed resistor has a fixed resistance value independent of an operating frequency, and includes at least one resistance device. The variable resistor has a variable resistance value that varies corresponding to a variation of the operating frequency. The input node receives the input voltage, and the output node outputs an output voltage, which includes the input voltage divided based on the fixed resistance value and the variable resistance value.
