Summary This work focuses on simulation and modeling of integrator leakage in a continuous time (CT) ΔΣ-modulator. The resolution of a ΔΣ-modulator is affected by the integrator leakage that limits the noise characteristics in the low frequency range and at DC. The model describes charge injection and charge sharing when the polarity of the I-DAC (current digital to analog converter) alternates or...
