Abstract
An apparatus for enhancing the slew rate of a differential amplifier capable of producing an output voltage and including a load stage, includes: a gain enhancement stage coupled to the load stage; a current comparator coupled to the differential amplifier and capable to compare a reference current value with a comparison current value; and a current mirror coupled to the current comparator and to the differential amplifier and capable to generate a slew rate enhancement bias current to enhance the slew rate of the output voltage when the comparison current value is greater the reference current value.
