Supply-Variation-Tolerant Transimpedance Amplifier Using Non-Inverting Amplifier in 180-nm CMOS
This paper presents a supply-variation-tolerant transimpedance amplifier (TIA). For parallel 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.
