A four-path time interleaved current steering DAC is presented. It requires the same number of unity current generators of the plain counterpart, thanks to the use of a digital ΣΔ modulator, thus leading to a lower number of unity current switchings. The benefit is that the non-linearity caused by clock feedthrough is attenuated. Behavioral level simulation results show that the SFDR of a 12-bit DAC operating at 12 GS/s can be 60 dB.
