Title:
CONTROLLED CONTINUOUS RAMP CONVERTER AND CONVERTING METHOD
Document Type and Number:
Japanese Patent JP3193328
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To economically constitute a high density neural network neuron by analogically and directly constituting a circuit required for the continuous function conversion of a neural network output function and a ramp function and providing a differentiation possible function in an output function.
SOLUTION: A controlled continuous ramp converter is constituted of three analog switches S1-S3 and two metal oxide film semiconductor electric field effect transistors M1 and M2. The on/off states of the analog switches S1-S3 are controlled by an input signal from an outside. When the analog switch S1 becomes the off-state and only the analog switch S2 becomes the on-state, a voltage V0 which is applied and stored in a capacitor C through the use of a transmission characteristic being equal to or below a critical value is utilized is limited to a max. value and a min. value by an operation controlled by the current I of the metal oxide film semiconductor electric field effect transistor M1 and the current I of the metal oxide film semiconductor electric field effect transistor M2 and respective approximate values of them are converted into the differentiation possible connecting function of an index function so as to be stored in the capacitor C.
