Abstract
System and method for generating one or more ramp signals. The method includes an oscillator configured to generate at least a clock signal, and a ramp signal generator configured to receive at least the clock signal and generate a first ramp signal. Additionally, the ramp signal generator is coupled to a first resistor including a first terminal and a second terminal. The first resistor is configured to receive an input voltage at the first terminal and is coupled to the ramp signal generator at the second terminal. Moreover, the first resistor is associated with a first resistance value. Also, the clock signal is associated with at least a predetermined frequency. The predetermined frequency does not change if the input voltage changes from a first magnitude to a second magnitude. The first magnitude is different from the second magnitude.
