Abstract
A system and method for distortion mitigation. In some embodiments, a system, includes: a transmitter, including: a pulse amplitude modulation driver circuit. The pulse amplitude modulation driver circuit may include a main driver including a most significant bit (MSB) amplifier, and a least significant bit (LSB) amplifier. The LSB amplifier may include an upper arm and a lower arm, a strength of the upper arm or a strength of the lower arm being adjustable.
