Abstract:A new method of modulating a signal, using Sigma Delta modulation in conjunction with switching-and sub-sampling mixers, is presented. Besides the normal functionality provided by the mixer an additional mixing or modulation function can be achieved with a small modification to the existing mixer. This modification can be carried out on a big amount of mixers including the above mentioned. Although the principle was meant to be used to down convert analog signals the principle is general and can be used in dig… Show more
