Abstract:
An estimation unit for estimating a nonlinearity error of a conversion circuit, such as an ADC, is adapted to receive a continuous-time input signal and output a digital output signal. In at least one embodiment, the continuous-time input signal is essentially bandlimited to an angular frequency band [ω1, ω2], where ω1>(L−1)π/T, ω2
