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 WebAug 30, 2024 · DC offset manifests itself as a large spike in the center of the spectrum. This happens in direct conversion receivers due to a few different factors. One is at the ADC where being off by a single LSB will yield a DC offset. Another is at the output of the low-pass filters where any DC bias will propagate through.
