Abstract

The design of a Digital-Based Operational Transconductance Amplifier (DIGOTA) featuring pseudo-CMOS bootstrap inverters integrated in a 600 nm Indium-Gallium-Zinc-Oxide (IGZO) Thin-Film Transistors (TFT) Flexible Integrated Circuits (FlexICs) technology is presented in this paper. Based on post-layout simulations, the proposed DIGOTA operates at 3 V power supply and achieves a DC gain of 33.8 dB and a GBW of 64.9 kHz at 221 µW power. Despite maintaining performance comparable to the previous Flexible DIGOTA, this new design occupies 26% less area, requires less logical gates, and enhances the slew rate whilst maintaining reasonable energy efficiency and large signal figures of merit of 14.5 MHz·pF/mW and 50.2 V.pF/s.mW, respectively.
