    Abstract

    This paper presents the impact that gain, offset and timing mismatch in time-interleaved analog-to-digital converter (TIADC) have on digital receiver systems. An analysis of the mismatch errors shows the dependency of the different errors from the spectrum of the input signal. A discrete-time TIADC model is derived allowing to simulate the mismatch effects of the individual ADCs. Finally, simulations results present the performance degradation that can be expected by the usage of non-ideal analog-to-digital converters (ADC) sampling alternately the inphase and quadrature signals in a direct conversion receiver architecture when random data is processed.
