Nowadays, data converters are considered one of the most relevant blocks in electronics, having a large amount of applications. In the last years, a fast trend in different fields, such as in digital processing and in semiconductor industry, boosted the performance of analog-to-digital converters (ADCs) and of digital-to-analog converters (DACs).In this chapter a concise historical perspective and a brief background related to ADCs is given. The main architectures are referred, emphasizing the operation mode of successive approximation ADCs (SAR-ADCs) and of sigma-delta ( †) ADCs, taking into account their current relevance. Additionally, and given the purpose of this book, the usage of thin film technologies in circuits is analyzed, especially when they are applied in ADCs.

This paper presents a flexible fully integrated 4-bit successive approximation register (SAR) Analog-to-Digital converter (ADC), which is fabricated by unipolar n-type indium-zinc-oxide thin-film transistors. A bootstrap switch and a comparator with a pre-amplifier are proposed and employed to realize the SAR ADC. The fabricated SAR ADC achieves a sampling rate of up to 20 kHz and a peak signal-to-noise and distortion ratio (SNDR) of 22.9 dB, corresponding to an effective-number-of-bits (ENOB) of 3.52 bits. The static performance of −0.58/+0.37 LSB DNL and −0.49/+0.39 LSB INL is achieved.

“…Past TFT implementations of ADCs have either been on high-cost, non-uniform over large area and high leakage technologies [3], [4] or on non-industry compatible and with very short lifetime technologies [5]- [9], or very slow and not stable technologies [7]. Dual Gate (DG) etch-stop-layer (ESL) IGZO TFTs have fair stability, very low leakage currents, low fabrication cost and fair uniformity at room temperature fabrication [10] and are compatible with flexible substrate.…”

Metal-Oxide thin-film transistors (TFTs) present unique opportunities to develop robust, low-cost and transparent electronics that can mechanically endure on flexible and stretchable substrates over large area in an industry compatible technology. Analog to digital converters (ADC) are an essential part of the Internet-of-Everything, where a multitude of sensing applications are envisaged, such as temperature and pressure sensor tags on human skin. In this work, dual-gate InGaZnO TFTs (IGZO) are demonstrated to achieve a 6-bit successive approximation (SAR) C-2C ADC operated at a clock of up to 400Hz and a power dissipation of 52.2µW at a power supply of V dd =15V. The ADC achieves a differential nonlinearity (DNL) of 0.7LSB and an integral nonlinearity (INL) of 0.58 LSB using only n-type TFTs. A figure of merit (FoM) of 66.7nJ/c.s. is achieved from an ADC on flexible substrate.
