Abstract
This disclosure describes techniques for shifting the cross-point of a digital signal in an optical transmitter. The cross-point shifting techniques may use multiple differential transconductors with their common polarity outputs coupled together to shift the cross-point of a signal. Using multiple differential transconductors in this manner may increase the balance between the positive and negative polarities of the resulting cross-point shifted signal relative to other types of cross-point shifting techniques, which may improve the quality of an optical signal generated by an optical transmitter.
