摘要： An analog input signal is sampled, and the sampled analog input signal is converted to a digital value. A calibration value is also sampled, and a single bit of an N bit offset value is calculated from the sampled calibration value. The sampling operations are alternatively performed so that one bit of the offset value is generated for each generated digital value. For example, the process is repeated N times to calculate all N bits of the offset value while generating N digital values.

摘要： An adaptive biasing technique improves fully differential gain boosted operational amplifiers transient characteristics and reduces power consumption. An adaptive biasing module includes a bias generation module and a bias replication module. The bias generation module generates a first control signal (VCMNB) and the first control signal is applied as an output common mode of a differential booster (inside the bias replication module). The bias replication module is coupled to the bias generation module for equalizing a common mode of the differential booster with the first control signal (VCMNB).
