Abstract
Disclosed is a circuit including timer interleaved (TI) analog-to-digital converter (ADC) circuitry which generates digital output signals. Correction circuitry receives the digital output signals from the TI ADC circuitry and generates corrected output signals using weight values to correct time skew. The correction circuitry includes a derivative filter which removes frequency dependency between the weight values and input signals to the TI ADC circuitry. Weight updating circuitry receives the corrected output signals and generates updated weight values for the correction circuitry. The weight updating circuitry includes a notch filter which suppresses spectral content in the corrected output signals to cancel spurious correlations in the weight updating process.
