Abstract
An integrated cell for extracting a binary value based on a value difference between two resistors values, comprising: connection means for a binary reading of the sign of the difference between said resistors; and connection means for a modification of the value of one of said resistors to make said sign of the difference invariable.
Claims24
An integrated cell (1) for extracting a binary value based on a difference between two resistor values (Rd, Rg;
- Rp1, Rp2), comprising:
- connection means for a binary reading of the sign of the difference between said resistors;
- and
- connection means for a modification of the value of one of said resistances to make said difference sign invariable.
