better understanding of the underlying principles of the human brain and root causes of its malfunctions. The majority of the ongoing research is conducted on animal models and there is a considerable demand for microsystems that can simultaneously record neural signals from a large number of electrodes in animals that are awake [1,2]. For decades, researchers have been using racks of bulky data-acquisition systems, connected to electrodes through a bundle of thin wires and a pre-amplifier headstage. Wires are wideband and easy to use. However, they can potentially bias the animal behavior and add noise and motion artifacts to the recorded signals. Thus, neuroscientists are interested in replacing the wire bundles with a wireless link and continue recording and
