Abstract :
A novel switched-capacitor integrator is discussed, of which the sampled-data transfer function is related to that of a continuous-time integrator by the bilinear z-transform. In contrast to the structures presented so far in the literature, influence of the parasitic capacitances is here reduced by the open-loop gain of the operational amplifier.
