Negative feedback is used to correct errors caused due to mismatch, process variation, temperature, or aging. A faster calibration cycle and smaller additional circuits are possible with analog calibration, compared to the more prevalent digital calibration techniques. The new calibration circuit is presented with the necessary theoretical details. To demonstrate this technique, a 10-bit binary-weighted CS DAC is implemented in a $$0.18\, \upmu \hbox {m}$$ 0.18 μ m CMOS process. With worst-case process parameter variations, simulated integral and differential nonlinearities of the calibrated DAC are less than $$\pm 0.32$$ ± 0.32 LSB. The DAC occupies an area of approximately $$0.3\,\hbox {mm}^{2}$$ 0.3 mm 2 .
