The invention provides a method of gain error calibration in a pipelined analog-to-digital converter (ADC). In one embodiment, a first stage and a second stage of the pipelined ADC share a common operational amplifier. The first stage is requested to generate the stage output signal ther
The invention provides an analog-to-digital converter (ADC). The ADC comprises a plurality of stages connected in series, a gain error correction module, and a look-ahead module. Each of the stages derives a stage output value from a stage input signal and generates a stage output si
The invention provides a method for gain error estimation in an analog-to-digital converter. In one embodiment, the analog-to-digital converter comprises a plurality of stages. A series of correction numbers applied to a target stage selected from the stages are correlated with a ser
