Weboffset is already input referred and the DOTB simulations yielded a sensitivity of 1 V/V, as expected. In the second test the same 10mV threshold voltage mismatch was applied to M3-M4, the NMOS regenerative pair. This resulted in a 26mV input referred offset voltage and a sensitivity of 2.6 V/V. While this at first seemed counter intuitive, further WebDC offset at A/D input: 10mV Single WCDMA carriers can also serve as interferers, as detailed in section 7.5.1.
