(editor) Publication year 2019 Abstract This work describes integrated readout electronics for on-panel fingerprint detection, focusing on two key building blocks: charge sense amplifier (CSA) and analog-to-digital converter (ADC). The CSA has been realized in a dual-gate self-aligned IGZO thin-film transistor (TFT) technology with channel length downsizing to 3µm, enabling 1.3mm bezel size for the peripheral readout electronics and 1fps readout of a 1-Mpixel 500dpi sensor array. The ADC has been realized in two different transistor technologies, IGZO and Indium-Tin-Zinc-Oxide (ITZO). The ITZO ADC achieves a sampling rate of 1kS/s, which is 7.5x faster compared to the IGZO ADC, due to the larger mobility of ITZO.
