Abstract
Switched capacitor topologies currently in use are susceptible to the deleterious effects of the parasitic capacitances associated with the switches. Topologies that are immune to these effects are disclosed. A first such embodiment comprises a first switch (22, 32), a capacitor (23, 33), and a second switch (24, 34) connected in series between one input terminal (1) and one output terminal (3) of the network. Third and fourth switches (26, 35 and 27, 36) are connected between the junctions (98, 42 and 99, 43) of the capacitor and the first and second switches, respectively, and the common junction (97, 41) of the second input and second output terminals (2, 4). A second embodiment is also disclosed.
