Latest Patents

One of Kai Cheung Chung's notable patents is focused on DC offset cancellation for a multi-stage amplifier. This invention provides a multi-stage amplifier that incorporates DC offset cancellation. The amplifier features a plurality of series-connected gain stages, each comprising a differential amplifier unit that generates a pair of differential outputs from a pair of differential inputs. Notably, a trailing stage in the gain stages includes a digital DC offset cancellation module designed to compensate for the DC offset of the trailing stage's differential amplifier unit. The digital DC offset cancellation module consists of a comparator that is coupled to the pair of differential outputs of the trailing stage's differential amplifier unit, receiving these outputs as inputs for the comparator. The comparator is designed to have an inherent DC offset that is substantially small. Additionally, it is preferable for a non-trailing stage of the amplifier to include an analog DC offset cancellation module to compensate for the DC offset of that stage.
