Abstract(in English) | A compact multiplier circuit is designed by time-encoded stochastic computing technology. The operands of multiplication are represented by the cycle duty of pulse signals. Using the Neuron-MOS technology, an efficiently tunable pulse-generator is proposed without digital pulse-width-modulation (PWM). The multiplication of two time-encoded stochastic numbers is obtained through a simple logic gate. The proof-of-concept multiplier is designed in a 0.18um CMOS technology. The total amount of MOS transistors is reduced to 3% of the traditional time-encoded stochastic calculator. From the circuit simulation results, the calculation accuracy of 85% is achieved; and the energy for one single operation is slightly reduced from the existing works with 5 x speed. |
