We propose an extremely energy-ecient mixed-signal approach for performing vector-by-matrix multiplication in a time domain. In such implementation, multi-bit values of the input and output vector elements are represented with time-encoded digital signals, while multi-bit matrix weights are realized with current sources, e.g. transistors biased in subthreshold regime. With our approach, multip...

An internally analog, externally digital architecture for parallel vector–matrix multiplication is presented. A threetransistor unit cell combines a single-bit dynamic random-access memory and a charge injection device binary multiplier and analog accumulator. Digital multiplication of variable resolution is obtained with bit-serial inputs and bit-parallel storage of matrix elements, by combini...

We present a new type of pFET synapse; by degenerating the source, the oxide currents provide stabilizing feedback to the oating gate and to the drain. We present experimental measurements from a oating-gate synapse that simultaniously computes four-quadrant products of its input and weight values, and computes a four-quadrant correlation, typical of hebbian and backpropagation learning rules, ...

This paper reports two speci c improvements in the nite-dimensional nonlinear dynamical modeling of marine thrusters. Previously reported four-quadrant models have employed airfoil theory considering only axial uid ow and using sinusoidal lift/drag curves. First, we present a thruster model incorporating the e ects of rotational uid velocity and inertia on thruster response. Second, we report a...
