A 3.3 V 6-Bit 100 kS/s Current-Steering Digital-to-Analog Converter Using Organic P-Type Thin-Film Transistors on Glass

Hybrid Systems in Foil (HySiF) exploiting ultra-thin flexible chips

“…1 is presented here. The smart skin may include thin chips (see Section 2.3) or printed devices [19] such as thin-film strain gauges driven by an organic thin-film transistor (OTFT) matrix for stress sensing (using the OTFT technology from [20]), printed antennas for wireless communication, a thin-film status display [21], a thin-film battery [22] and thin, flexible chips for control and transmit functions.…”

Modeling of Drain Current Mismatch in Organic Thin-Film Transistors

“…The local charge fluctuation is proportional to threshold voltage fluctuations as follows: (6) where is the dielectric capacitance per unit area, is the local fluctuation of the threshold voltage . From the standard deviation [6], the mean square of is expressed as (7) where is the channel width and is a constant reflecting the uncertainty in the number of charge carriers in the accumulation layer.…”

“…From the standard deviation [6], the mean square of is expressed as (7) where is the channel width and is a constant reflecting the uncertainty in the number of charge carriers in the accumulation layer. We assume a Poisson distribution [13], [17]for the fluctuation of charge carriers, then (8) Fig.…”

“…A few advanced examples have already been demonstrated, such as radio-frequency identification (RFID) tags [3], [4], digital-analog converters (DAC) [5], [6], and analog-digital converters (ADC) [7]. The complexity of integrated circuits at large-scale requires accurate models to describe transistor behaviors.…”

Radio frequency electronics on plastic

“…A ring oscillator with signal delays as short as 230 ns per stage was demonstrated using organic FETs [10]. A 3.3 V 6-bit 100 kS/s current-steering digital to analogue converter (DAC) using organic TFTs on glass was presented in [11]. To improve the speed, carbon nanotube transistors were applied for logic circuits with the vision to be used for large area electronics [12].…”
