“…Furthermore, the bias point is set by the current balance of two transistors both biased in saturation with a relatively large overdrive, enabling rather limited sensitivity to process parameter variations (Figure 3.3b). For reasonably well matched mobility and threshold voltage values, symmetric VTCs are achieved, which generally allow direct-coupled multistage amplifiers [7], [8], [124], [125].…”

Recent years have witnessed significant research efforts in flexible organic and amorphous-metal-oxide analogue electronics, in view of its formidable potential for applications such as smart sensor systems. This Element provides a comprehensive overview of this growing research area. After discussing the properties of organic and amorphous-metal-oxide technologies relevant to analogue circuits, this Element focuses on their application to two key circuit blocks: amplifiers and analogue-to-digital converters. The Element thus provides a fresh look at the evolution and immediate opportunities of the field, and identifies the remaining challenges for these technologies to become the platform of choice for flexible analogue electronics.

“…Further, the shift amount of TFT's current-to-voltage characteristics more likely to increase under illumination. For the conventional sensing approaches, TFTs are used for light-tocurrent converting, and lots of calibration steps are required for the external readout circuit to get the exact value of light intensity [7]. And complicated external readout circuit including amplifier, analog-to-digital converters are usually needed [8].…”

A reliable digital thin-film transistors (TFTs) integrated ambient light sensor is proposed. The circuit structure is simple, as only 6 TFTs and 2 capacitors are required. The intensity of ambient light is presented by the number of voltage pulses at the output terminal of the light sensor. The operating principal of the sensor are detailed, and SPICE simulations are performed to explore the relationship between the number of output pulses and the light-induced leakage current. The feasibility of the circuit is further proved by measurements of fabricated circuit samples with the standard a-Si:H TFTs process.

May. 2018 TCAS-I 1611Abstract-This paper presents the first printed organic 13-MHz RFID on flexible substrate. The proposed solution includes a planar near field antenna bonded to an RFID tag, which is printed on flexible foil using an organic complementary TFT technology. Thanks to an active envelope detector, ASK modulation with modulation depth as low as 20% can be adopted to increase the available input power for the rectifier. The RFID functionality is demonstrated at the internally generated supply voltage of 24 V, for a reading range of 2-5 cm and a bit-rate up to 50 bit/s. With more than 250 transistors on the same foil, this work represents the most complex circuit ever published in a printed organic complementary TFT technology.Index Terms-ASK modulation, active detection, mixed analog-digital circuits modulation index, organic circuits, pentacene, polyimide, radio frequency identification, sub...
