| description | An analog input stage has m differential input channels, wherein m>1. The analog input stage is configured to select one of the m differential input channels and provide an output signal. The analog input stage has n identical selection units each having m differential channel inputs and one differential output, wherein n is at least 2m−1. Each selection unit is operable to be coupled to any of the differential input channels through respective differential multiplexer units, wherein the multiplexor units are driven to select one of the differential input channels and couple the selected differential channel input through a butterfly switch unit with the differential output of the selection unit. The differential output signals of the n selection units are combined whereby unwanted crosstalk from channels other than a selected channel are removed by cancellation. |
