integration of optical transceivers, supply voltage variation is one of the serious problems.
We propose a TIA using a non-inverting stage to cancel the supply variation. As a proof of
concept, we fabricated the proposed TIA in a 180-nm CMOS. We measured the eye-
diagrams with various supply voltages. Measurement results show that the voltage swing
and the eye-opening voltage are improved by 105% and 180%, respectively.
