A magnetoresistive multi-level generator (50) including a first series circuit (52) with a first magnetoresistive element (54) having a resistance equal to Rmax connected in series with n first magnetoresistive elements (55-57) each having a resistance equal to Rmin. Where n is equal to a whole integer greater than one, n additional series circuits, each including an additional magnetoresistive element with a resistance equal to Rmax connected in series with n magnetoresistive elements each with a resistance equal to Rmin. The first and n additional series circuits being connected in series between the input (A) and output (B) terminals and in parallel with each other. Whereby a total resistance between the input and output terminals is a level Rmin + DELTA R/n, where DELTA R is equal to Rmax - Rmin. |
