ABSTRACT:
A comparator component having a comparison circuit and bias generator circuit, with the bias generator circuit also having a same number of transistors connected in an identical configuration, as those contained in the comparison circuit to generate a comparison result based on the bias signal generated by the bias generator circuit. A transistor of the comparison circuit receiving the bias signal is connected to a corresponding transistor in the bias generator circuit, in a current mirror configuration. The same bias circuit may be shared by many comparison circuits of corresponding comparator components. The features can be extended to provide hysteresis.
