| Four-quadrant synapse stuu In our rst treatments of single-transistor synapses ((1], 2]; elaborated in 3]), we presented the electron-tunneling, hot-electron{injection, and multiplicative behavior of these devices. We used a feedback connguration to characterize the tunneling and hot-electron injection phenomena in these synapses 3]. We also derived an eeective learning rule, but we did not c...

Multiplier and divider circuits are usually required in the fields of analog signal processing and parallel-computing neural or fuzzy systems. In particular, this paper focuses on the hardware implementation of fuzzy controllers, where the divider circuit is usually the bottleneck. Multiplier/ divider circuits can be implemented with a combination of A/D-D/A converters. An efficient design base...

This paper explores whether analog circuitry can adequately perform constrained optimization. Constrained optimization circuits are designed using the differential multiplier method. These circuits fulfill time-varying constraints correctly. Example circuits include a quadratic programming circuit and a constrained flip-flop.

This paper describes the jitter problem in DLL-based clock multipliers that arises due to stochastic mismatch in the delay cells that are used in the Voltage Controlled Delay Line of the DLL [1]. An analysis is presented that relates the stochastic spread of the delay of the cells to the output jitter of the clock multiplier. This analysis shows that relative time deviations are highest in the ...
