Patent attributes
A current data compression circuit of which output current value is accurate even when transistors with large variations in electrical characteristics are used. The current data compression circuit is an electronic circuit comprising a drive element including a plurality of transistors and a means for switching over a series connection state and a parallel connection state of the transistors. An inputted current is compressed for output by the current data compression circuit. Or, the current data compression circuit is an electronic circuit comprising a drive element including a plurality of transistors in which the transistors are used in parallel connection states when inputting current and in series connection states when outputting current.
