ABSTRACT:
Control-type continuous ramp converting apparatus and method therefore. The present invention provides real-time processing of neurons in the neural network, easy implementation and reduction of manufacture cost of high density neurons in the neural network. The present invention comprises a first voltage controlling part for receiving a first voltage from an outside, and for non-linearly increasing a charged voltage in accordance with a differential continuous function of an exponential function; a second voltage controlling part for receiving a second voltage from an outside, and for non-linearly reducing a charged voltage in accordance with a differential continuous function of an exponential function; a charging part for charging an input current, and for providing the charged voltage of the charging part with the second voltage controlling part and an outside; and a plurality of switches for coupling outside and the first and the second voltage controlling part to the charging part, for selectively providing a third voltage from outside, an increased voltage and a decreased voltage based on the voltage of the charging part.
