Effect of MOSFET variability including RDF and LER on STDP. (a) STDP behavior for 200 Monte Carlo simulation results (gray) and no variability (red). Each behavior was obtained with a different set of MOSFET parameters. (b) Distribution of initial synaptic weight, plotted from 200 Monte Carlo runs. (c) Synaptic evolution for 200 circuits given random MOSFET mismatch. The protocol in use was identical to that in Fig. 6(e) in attempt to lead V w2 to potentiation. (d) The distribution of V w1 and V w2 at 100 s.
