This standard describes the most common sources of measurement error and gives recommended practices in order to minimize and/or characterize the effect of each. Standa

Disclosure of environmental conditions and design-of-experiment are included so that results can be appropriately assessed by the research community. These reporting practices also support repeatability of

29、 results, so that new discoveries may be confirmed more efficiently. The practices in this standard were compiled from research and industry organizations developing organic transistor devices, materials, circuitry, and manufacturing techniques. These practices are based on standard operating proced

30、ures utilized in laboratories worldwide. The development of this standard was initiated in 2004 to facilitate the evolution of organic transistor circuitry from the laboratory into a sustainable industry.

Overview 1.1 Scope This standard describes a method for characterizing organic electronic transistor-based ring oscillators, including measurement techniques, methods of reporting data, and

36、the testing conditions during characterization. 1.2 Purpose The purpose of this standard is to provide a method for systematically characterizing organic transistor-based ring oscillators. This standard is intended to maximize reproducibility of published results by providing a framework for testing

37、 organic ring oscillators, whose unique properties cause measurement issues not typically encountered with inorganic-based circuitry. This standard stresses disclosure of the procedures used to measure data and extract parameters so that data quality may be easily assessed. This standard also sets g

38、uidelines for reporting data, so that information is clear and consistent throughout the research community and industry. 1.3 Electrical characterization overview 1.3.1 Testing apparatus Testing shall be performed using an electronic device test system with an accuracy and resolution of at least 0.1

39、% of the measurement values for both signal level and timing or frequency measurements. In order to maintain the necessary accuracy, this test method requires that the instrumentation be calibrated against a known and appropriate set of standards e.g., National Institute of Standards and Technology

40、(NIST). These calibrations may be performed by the equipment user or as a service by the equipment vendor. Calibration is not performed against a known organic field-effect transistor (OFET), organic circuit, or other FET-type device; the basic instrument operations (e.g., voltage, current, and resi

41、stance) are calibrated 2 IEC 62860-1:2013(E) IEEE Std 1620.1-2006 Published by IEC under license from IEEE. 2006 IEEE. All rights reserved. against some method traceable to a NIST (or similar internationally recognized standards organization) physical standard. Recalibration is required according to

42、 the instrument manufacturers recommendations or when the instrument is moved or when the testing conditions change significantly (temperature change greater than 10 C, relative humidity change greater than 30%, etc.). 1.3.2 Measurement techniques 1.3.2.1 Required measurements Characterization of th

43、e organic ring oscillator shall include at minimum the following primary set of measurements: g127 A ring of an odd number (at least three) of inverter stages, operated at a single supply voltage, characterizing output voltage from a single node versus time in seconds. The number of inverter stages

44、should be chosen to be as large as practically possible. Ideally the ring oscillator should comprise at least seven or more stages. Shorter ring oscillators can often oscillate with signal level not closely related to their saturation values. While this results in faster oscillation, the timing numb

45、ers so obtained are much less useful in understanding realistic digital circuit speeds. In addition, ring oscillators with few stages are more affected by the way in which the output voltage is measured, and, in particular, measurement results will depend more on the capacitance with which the node

46、being measured is loaded by the measurement. For all ring oscillators particular care should be taken to report the conditions of the signal measurement at the output node. In all cases the value of the load capacitance in relation to the input capacitance of an inverter stage should be reported. g1

47、27 Both output frequency and output signal level and swing shall be reported. g127 Static measurements of inverter transfer characteristics. Preferably, the inverters for static measurements should have the same size and geometry as those used in the ring oscillator. Geometry information shall be pr

48、ovided for both ring oscillators and static inverters. 1.3.2.2 Recommended measurements The following additional measurements are strongly recommended: g127 Measurement of ring oscillator output using multiple supply voltages. g127 Simultaneous measurement of ring oscillator output at two or more no

49、des, using buffer stages between the ring oscillator and measurement apparatus. This is in addition to, and should not be instead of, measurement of ring oscillator output at one node. 1.3.3 Repeatability and reporting sample size Sample performance between different devices may vary due to variations in the fabrication process. Additionally, it is useful to determine the repeatability of the reported results. Therefore, sample size is to be reported thus: g127 If no sample size is reported, it is assumed that the data represents a samp
