<p>Operational transconductance amplifiers (OTAs) (10, 12) are combined at their outputs, yielding a single frequency compensation connection point (16). In a preferred embodiment, the output of each OTA is asymmetric, i.e., they can only source current and the OTA outputs are tied together to a constant current sink (14). Consequently, the OTA that sources more current controls the voltage of the merged output. This merged output point provides a voltage output that may be used as a frequency compensation point.</p> |
