A 3.3V 6b binary-weighted current-steering D/A converter using organic p-type thin-film transistors (OTFTs) is presented. The circuit occupies 12mm2 and is fabricated on a glass substrate using silicon stencil shadow masks. The converter consumes 260μW at an output swing of 2V and has a maximum update rate of 100kS/s. The measured DNL and INL at an update rate of 1kS/s are -0.69LSB and
1.16LSB, respectively. For sinusoids between 31Hz and 3.1kHz, the minimum SFDR is 32dB.
