<p>Common mode errors may be sensed and corrected by receiving an output signal 105 - 106 and comparing the output signal 105 - 106 with a predetermined signal level. When the output signal 105 - 106 is in a first relationship with respect to the predetermined signal level a source current is provided to a integrating element 110. If, however, the output 105 - 106 is in a second relationship with respect to the predetermined signal level, a sink current is provided to the integrating circuit element 110. Regardless of whether a sink or source current is provided to the integrating circuit element 110, the integrating circuit element 110 generates a common mode information signal 123 which is used to correct for common mode errors.</p> |
