Summary form only given. A method to extract compact circuit models for one-dimensional nanostructures from measured high-frequency characteristics is described. We demonstrate that a frequency-independent parallel RC circuit is the simplest model that accurately describes high-frequency electrical conduction in carbon nanofibers. The resistance is determined from dc measurement and the capacitance...
We present the first, fully integrated, multi-channel implementation of a patch-clamp measurement system. The system was implemented in a 0.5 μm silicon-on-sapphire process. The system can record two simultaneous cell membrane currents up to ±20 μA with a rms noise of 8 pA in a 10 kHz bandwidth. The system can compensate for the capacitance and resistance of the pipette electrode, up to 10 pF and...
