Relaxation digital-to-analogue converter

The novel relaxation digital-to-analogue conversion technique, which takes advantage of the exponential impulse response of a first-order RC network to generate binary weighted voltages, is proposed to design standard-cell based, mismatch-insensitive, ultra-low power, tiny digital-to-analogue converters targeting the requirements of Internet of Things (IoT) applications. The effectiveness of the approach is validated by simulations and measurements performed on a proof-of-concept 10 bit, 300 S/s FPGA prototype.
