Abstract
In this paper we show two different schemes to implement a field programmable circuit that can connect n capacitors as a charge-pump of, eventually, any topology and switching pattern. Capacitor connectivity is configured by means of registers that control multiplexers that, in turn, select the phase signal that controls each switch. It is also shown that, with any of these schemes, dynamic configuration of the circuit may be achieved by simply adding additional control phases
