Printed electronic components offer certain technological advantages over their silicon based counterparts, like mechanical flexibility, low process temperatures, maskless and additive manufacturing possibilities. However, to be compatible to the fields of smart sensors, Internet of Things and wearables, it is essential that devices operate at small supply voltages. In printed electronics mostly silicon dioxide or organic dielectrics with low dielectric constants have been used as gate isolators, which in turn has resulted in high power transistors operable only at tens of volts. Here, we present inkjet printed circuits which are able to operate at supply voltages as low as ≤ 2 V. Our transistor technology is based on lithographically patterned drive electrodes, the dimensions of which are carefully kept well within the printing resolutions; the oxide semiconductor, the electrolytic insulator and the top-gate electrodes have been inkjet printed. Our inverters show a gain of ∼ 4 and 2.3 ms propagation delay time at 1 V supply voltage. Subsequently built 3-stage ring oscillators start to oscillate at a supply voltage of only 0.6 V with a frequency of ∼ 255 Hz and can reach frequencies up to ∼ 350 Hz at 2 V supply voltage. Furthermore, we have introduced a systematic methodology for characterizing ring oscillators in the printed electronics domain, which has been largely missing. Benefiting from this procedure, we are now able to predict the switching capacitance and driver capability at each stage, as well as the power consumption of our inkjet printed ring oscillators. These achievements will be essential for analyzing the performance and power characteristics of future inkjet printed digital circuits.The application domains such as Internet of Things (IoT), smart sensors and wearables may benefit from printed electronics (PE) technology where the devices can be printed onto flexible or rigid substrates. Most of the devices in PE, are based on organic materials and suffer from high supply voltage requirements (> 10 V). 1-3 On the other hand, some examples of low voltage organic devices can also be found in the literature. 2,4-10 The reasons behind the need of high supply voltages is the low carrier mobility of p-type organic materials and low performance of printed or vacuum deposited gate dielectrics that have been used. In addition the scarcity of n-type organic semiconductors and p-type inorganic semiconductors leads to missing complementary circuits in both domains, 11 except their realization in hybrid systems. 2,12 Lithographically patterned ring oscillator structures based on organic field-effect transistors (OFETs) are able to perform at high frequency (200 kHz) but at the same time require high supply voltage (-60 V). printed, based on OFETs operate at high supply voltages (∼ −40 V) with frequencies below 5 Hz. 14,15 An OFET based 11-stage ring oscillator operating at only 3 V supply with a frequency of 1.7 Hz was also reported in literature. 7 By using an complementary design, the frequency was increase...

“…It can be easily included in the model following the approaches [51,55,56,57,58]. The idea is to split the channel into a small contact region, where there is a voltage drop V C , and the main channel, where the voltage drop is V DS − V C .…”

“…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.
