Abstract:
An auto-tuned ramp generator and a method for generating a sawtooth signal are provided. In the method and apparatus, a sawtooth signal is compared to a first reference voltage and a second reference voltage. In response to determining that the sawtooth signal does not exceed the first reference voltage, the voltage level of the sawtooth signal is increased. In response to determining that the sawtooth signal exceeds the second reference voltage, the voltage level of the sawtooth signal is decreased. The voltage level the sawtooth signal is retained if the sawtooth signal remains between the first and second reference voltages.

Claim (Index 1):
A sawtooth signal generator, comprising:\n a sawtooth signal generation stage configured to:\n receive a control signal; and \n generate a sawtooth signal based on the control signal; \n a first comparator configured to:\n receive a first reference voltage; \n receive the sawtooth signal; \n compare the sawtooth signal with the first reference voltage; and \n output a first comparison signal that is asserted when the sawtooth signal exceeds the first reference voltage and deasserted when the sawtooth signal does not exceed the first reference voltage; \n a second comparator configured to:\n receive a second reference voltage; \n receive the sawtooth signal; \n compare the sawtooth signal with the second reference voltage; and \n output a second comparison signal that is asserted when the sawtooth signal exceeds the second reference voltage and deasserted when the sawtooth signal does not exceed the second reference voltage; and \n control logic configured to:\n receive the first and second comparison signals; \n determine whether the first comparison signal is deasserted; \n in response to determining that the first comparison signal is deasserted, output the control signal as a digital multibit signal commanding the sawtooth signal generation stage to increase a slope of the sawtooth signal; \n determine whether the second comparison signal is asserted; and \n in response to determining that the second comparison signal is asserted, output the control signal as the digital multibit signal commanding the sawtooth signal generation stage to decrease the slope of the sawtooth signal.
