  • Publication number: 20230049903
    Abstract: System and method for generating one or more compensation currents for a DC-to-DC voltage converter. For example, a system for generating one or more compensation currents for a DC-to-DC voltage converter includes: a voltage generator configured to receive a reference voltage and generate a first ramp voltage and a second ramp voltage based at least in part on the reference voltage; and a current generator configured to receive the first ramp voltage, the second ramp voltage, an input voltage, and an output voltage; wherein the current generator is further configured to: if the output voltage is smaller than the input voltage, generate a first compensation current based at least in part on the first ramp voltage; and if the output voltage is larger than the input voltage, generate a second compensation current based at least in part on the second ramp voltage.
