this paper describes a phase-locked loop (PLL) designed for clock multiplication in a LVDS transmitter. The PLL consists of a novel low-jitter charge-pump, a fully differential ring-oscillator based VCO, a dynamic-logic PFD, a 2nd order passive loop filter ...
Abstract—Mapping neuronal networks activity of in-vitro cell cultures with microelectrode array (MEA) based systems, providing a spatial resolution down to cellular/sub-cellular levels and an adequate temporal resolution for resolving action potential prop ...
Abstract—A platform based on an active-pixel-sensor electrode array (APS-MEA) for high-resolution imaging of invitro electrogenic cell cultures is presented, characterized and validated under culture conditions. The system enables full frame acquisition at ...
This paper presents a chip-based electrophysiological platform enabling the study of micro- and macro-circuitry in in-vitro neuronal preparations. The approach is based on a 64 x 64 microelectrode array device providing extracellular electrophysiological a ...
Large network monitoring of electrogenic cells by means of micro electrode arrays (MEA) has become a valuable methodology in electrophysiology. In order to understand the mechanisms of learning (plasticity) and memory in fundamental neuroscience it is impe ...
