Dc offset single tone test

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 WebENOB, SFDR, and Other Single Tone Measurements ADCs are often characterized by their Effective Number of Bits (ENoB), Spurrious-Free Dynamic Range (SFDR), and other similar measurements. These quantities are derived from a single tone test.
