A new topology for a three-stage Operational Transconductance Amplifier (OTA) in flexible-substrate process is presented. The amplifier is designed in the Cadence environment using thin-film transistors (TFTs) and is validated through post-layout simulations. When loaded with 50-pF capacitive load, the OTA exhibits 52-dB gain and 1.19-\text{MHz} gain-bandwidth product with 3-\text{V} power-supply voltage and 186-\mu \text{W} power dissipation. The OTA is compared to other flexible TFT amplifiers in terms of bandwidth, drive capability and power dissipation. It shows the best figure-of-merit with performance that ranges from 8.57X to 1750 X compared to other state-of-The-Art solutions.

Abstract
A new topology for a three-stage Operational Transconductance Amplifier (OTA) in flexible-substrate process is presented. The amplifier is designed in the Cadence environment using thin-film transistors (TFTs) and is validated through post-layout simulations. When loaded with 50-pF capacitive load, the OTA exhibits 52-dB gain and 1.19-\text{MHz} gain-bandwidth product with 3-\text{V} power-supply voltage and 186-\mu \text{W} power dissipation. The OTA is compared to other flexible TFT amplifiers in terms of bandwidth, drive capability and power dissipation. It shows the best figure-of-merit with performance that ranges from 8.57X to 1750 X compared to other state-of-The-Art solutions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
