A Novel Complex Gm-C IF Sub-Sampling Mixer

Christian Enz, Aravind Prasad Heragu Singaiyengar

In this paper, a novel circuit referred to as complex Gm-C sampler that can be used for sub-sampling IF signals is presented. The circuit employs a conventional cross-coupled Gm-C filter structure with a built-in sampler to combine th ...
