Abstract
An offset error compensation system is provided that includes a comparator ( ) having an offset error ( ), a positive receptor ( ), a negative receptor ( ), a positive output ( ), and a negative output ( ). A sequence generator ( ) generates control signals (22) representing normal cycles and swap cycles. A first cross connect ( ) is coupled to the positive receptor ( ), the negative receptor ( ), a positive input signal ( ), and a negative input signal ( ). The first cross connect ( ) couples the positive input signal ( ) to the positive receptor ( ) and the negative input signal ( ) to the negative receptor ( ) in response to a normal cycle. The first cross connect ( ) further couples the positive input signal ( ) to the negative receptor ( ) and the negative input signal ( ) to the positive receptor ( ) in response to a swap cycle. A second cross connect ( ) is coupled to the positive receptor ( ), the negative receptor ( ), the positive output ( ), and the negative output ( ). The second cross connect ( ) couples the positive receptor ( ) to the positive output ( ) and the negative receptor ( ) to the negative output ( ) in response to the normal cycle. The second cross connect ( ) further couples the positive receptor ( ) to the negative output ( ) and the negative receptor ( ) to the positive output ( ) in response the swap cycle.
