Methods and systems for split voltage domain receiver circuits are disclosed and may comprise amplifying complementary received signals in a plurality of partial voltage domains, and combining the amplified received signals, utilizing a stacked cascode amplifier for each domain, into a single differential signal in a single voltage domain. The stacked cascode amplifiers may comprise a feedback loop having a comparator which controls a current source in each domain. The complementary signals may be received from a photodiode, which may be integrated in the integrated circuit. The amplified received signals may be combined via stacked common source or common emitter amplifiers. The received signals via may be amplified by stacked inverters. The amplified received signals may be AC or DC coupled prior to the combining. The complementary received signals may be amplified and combined via cascode amplifiers. The voltage domains may be stacked and may be controlled by feedback loops.
