Abstract
A trans-conductance regulation circuit, a trans-conductance error amplifier module and a power converter. The trans-conductance regulation circuit provides a bias current at least partially based on an output voltage of the power converter. The bias current is sent to bias a trans-conductance operational amplifier in the trans-conductance error amplifier module so that a trans-conductance of the trans-conductance operational amplifier is direct proportional to the output voltage of the power converter. The power converter regulates the output voltage based on a negative feedback loop comprising the trans-conductance error amplifier module. The trans-conductance error amplifier module may help to maintain a band width of the negative feedback loop substantially stable and immune to variations in the output voltage.
