Abstract
The use of switched capacitors as wide-range, programmable resistive elements in spatially extensive artificial dendritic trees (ADT's) is described. We show that silicon neuromorphs with ADT's can produce impulse responses that last millions of times longer than the initiating impulse and that dynamical responses are tunable in both shape and duration over a wide range. The switched-capacitor resistors forming a dendritic tree are shown indirectly to have a useful programmable resistance range between 500 K Omega and 1000 G Omega. Experimental results are presented that show variable impulse response functions, tunable frequency selectivity, and rate-invariance of spatiotemporal pattern responses.Keywords
