Abstract :
A simple technique for significantly reducing the effect of the finite gain of amplifiers on the performance of switched-capacitor filters is presented. The effectiveness of this technique has been established by extensive simulation studies. This technique has the potential for simplifying amplifier design and extending the frequency range of switched-capacitor filters by trading gain for bandwidth.
