A level-crossing based circuit with offset voltage cancellation includes a first level-crossing detector section having a first output capacitor, wherein the first level-crossing section is configured to charge the first output capacitor to a first voltage corresponding to an input signal. The first voltage includes a first offset voltage. The level-crossing based circuit also includes a second level-crossing detector section having a second output capacitor, wherein the second level-crossing detector section is configured to discharge the second output capacitor to a second voltage corresponding to the input signal such that the second voltage includes a second offset voltage that is substantially equal in magnitude to the first offset voltage and opposite in polarity to the first offset voltage relative to an average of the first voltage and the second voltage.
