Apparatus for correcting setting error in an MDAC amplifier

Image Number 2 for United States Patent #7969334.

Multiplying digital-to-analog converters (MDACs), which are generally employed in pipelined analog-to-digital converters (ADCs), can have a settling error associated with the MDAC amplifier. Here, a circuit is provided that includes additional amplifiers and a capacitor network that compensates for this settling error. Thus, a more accurate pipelined ADC can now be produced.
