Abstract
An electronic device disclosed herein includes a current comparator to generate an output current based upon a difference between a current flowing in an output branch and a current flowing in an input branch. A pair of transistors is coupled to an output of the current comparator. A first amplifier has inputs coupled to the pair of transistors and to a reference voltage, the first amplifier being configured to subtract the reference voltage from a voltage across the pair of transistors and output a difference voltage. A second amplifier has inputs coupled to the difference voltage and to the reference voltage, the second amplifier being configured to subtract the difference voltage from the reference voltage and output a pulse skipping mode reference signal.
