Correction to "A 0.016 mm² 144-µW Three-Stage Amplifier Capable of Driving 1-to-15 nF Capacitive Load With >0.95-MHz GBW"

In the above-named article [ibid., vol. 48, no. 2, pp. 527-540, Feb. 2013], US Patent 7,646,247 (Jan. 12, 2010) was cited in the description of Fig. 8, for a more general description about the utilization and advantages of the G
_ma
stage. However, the article by U. Dasgupta "Issues in "Ahuja" frequency compensation technique," (Proc. IEEE Int. Symp. Radio-Frequency Integration Technology, 2009, pp. 326-329) exhibits the circuit implementation of the G
_ma
stage (improved Ahuja compensation circuit), which, for that reason, should have been referenced for completeness, as well. The authors would like to thank Dr. U. Dasgupta for pointing out this missing information.
