Title:
ARITHMETIC OPERATION DEVICE
Document Type and Number:
Japanese Patent JP2021111142
Kind Code:
A
Abstract:
To execute a product-sum operation.SOLUTION: An arithmetic operation device includes a comparator, M cross switches and M coefficient circuits. The comparator compares a first voltage generated at a first comparison terminal with a second voltage generated at a second comparison terminal. The M cross switches are provided for M input signals. The M coefficient circuits are provided for M coefficients and include a first constant current source and a second constant current source. Each of the M cross switches changes over from a straight state to a reverse state. In each of the M coefficient circuits, the first constant current source is connected between a positive output terminal of its corresponding coefficient circuit and a reference potential, and the second constant current source is connected between a negative output terminal of its corresponding coefficient circuit and the reference potential.SELECTED DRAWING: Figure 3
