Parasitic insensitive toggle-switched capacitor and its applications to switched-capacitor networks

A new parasitic insensitive toggle-switched-capacitor scheme is presented along with its applications to the synthesis of switched-capacitor networks. The scheme can be used to obtain a recently reported5 first-order inverting bilinearly transformed transfer function. The advantage of this technique is that, for the realisation of a lowpass filter, it requires only three capacitors and no matching conditions.
