Abstract :
A 3.3 V 6-bit binary-weighted current-steering digital-to-converter converter (DAC) using low-voltage organic p-type thin-film transistors (OTFTs) is presented. The converter marks records in speed and compactness owing to an OTFT fabrication process that is based on high-resolution silicon stencil masks. The chip has been fabricated on a glass substrate and consumes an area of 2.6× 4.6 mm2. The converter has a maximum update rate of 100 kS/s and a maximum output voltage swing of 2 V. The measured DNL and INL at an update rate of 1 kS/s are - 0.69 and 1.16 LSB, respectively. A spurious-free dynamic range (SFDR) of 32 dB has been measured for output sinusoids at 31 Hz (update rate of 1 kS/s) and 3.1 kHz (update rate of 100 kS/s).
