Mix mode wide range divider and method thereof
A mix mode wide range divider is provided for dividing a first signal by a second signal to generate an output signal. A third signal is generated depending on the resistance of a first adjustable resistor, and a fourth signal is generated according to the third signal and a target value determined by the second signal, to adjust the resistance of the first adjustable resistor and the resistance of a second adjustable resistor. The resistance of the first adjustable resistor is so adjusted to make the third signal equal to the target value, and the resistance of the second adjustable resistor is so adjusted to maintain a ratio of the resistance of the second adjustable resistor to the resistance of the first adjustable resistor. The output signal is generated depending on the first signal and the resistance of the second adjustable resistor.
