N2 - This work presents a compact multi-bit multi-order finite impulse response (FIR) digital-to-analog converter (DAC) design for internet of things (IoT). It is accomplished in 65-nm CMOS technology merging the 4-order FIR filter and 4-bit calibration-free DAC as one block. This FIR DAC achieves over -20-dB out-band noise filtering with 0-dBFS in-band signal input, and demonstrates a maximum integral nonlinearity (INL) and differential nonlinearity (DNL) of 0.26% and 0.12% in 502.5-mV full-scale range while consuming a power of 0.53-mW and occupying 0.052-mm2 area.
