Abstract
In the above paper, a mistake in the schematic diagram of the 0.5-V operational transconductance amplifier (OTA) (Fig. 11) was discovered by Prof. Dr. Martin Schubert of FH Regensburg, University of Applied Sciences, Regensburg, Germany. The original OTA circuit diagram shows two series combinations of a 5-kOmega resistor and a 20-pF capacitor connecting the outputs of the first stage to the inputs of the second stage, which is incorrect. The correct OTA schematic is shown in Fig. 1 below. The <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">RC</i> combinations are connected between the inputs and outputs of the second stage for Miller compensation with right-half-plane zero cancellation and the first and second stages are directly coupled. We apologize for this error.
