Abstract :
A z-transformation for the design of highpass switched-capacitor filters is considered, which refers to a properly designed lowpass filter. The possible switched-capacitor implementation uses the voltage inverter switch approach with fully differential SC recharging devices: therefore, a bilinear design is obtained which introduces one zero at ¿ = 0.
