Abstract :
Novel switched-capacitor stages which are free from the effects of op-amp DC offset voltage are described. The op-amps used in the stage need not slew between the desired output voltage and the offset voltage as in previously described offset-free circuits. The use of the new scheme in general applications is also discussed.
