Flexible 16nJ/c.s. 134S/s 6b MIM C-2C ADC using Dual Gate Self-aligned Unipolar Metal-Oxide TFTs

In this work a metal-oxide (Indium Gallium Zinc Oxide) 6-bit successive approximation metal-insulator-metal C2C analog to digital converter (ADC) fabricated on 15μm thick flexible substrate is demonstrated. The ADC is operated at a clock speed of 2kHz and at a power supply of 15V. The power dissipation including output buffers is 212μW at 15V and the a sampling rate of 134S/s. The ADC achieves a figure of merit (FoM) of 16.58nJ/c.s. and no missing codes using dual gate selfaligned n-type thin-film transistors on polymeric substrate.
