Abstract :
The paper describes a new type of the switched-capacitor integrator based on second generation current conveyor (CCII). Using the CCII instead of the standard operational amplifier allows the realization of the integrator with an enhanced frequency range. The proposed circuit has reduced sensitivity to the switches´ parasitic capacitance. A discussion of the theoretical analysis, as well as the result of a computer simulation, is included.
