Abstract:
A current converter having an impedance and providing a desired voltage and current to a load and comprising:a voltage/current source for supplying an input voltage, V.sub.in, and input current, I.sub.in ;a current-increasing charge pump having n stages of n-series connected input capacitors coupled to said voltage/current source for developing an output voltage, ##EQU31## across each capacitor, each capacitor having a positive and a negative output;an output capacitor having a corresponding input and output for coupling to said load;n parallel-connected input switches, each input switch being coupled to a corresponding one of the n input capacitors and being capable of alternately and synchronously moving from a first position to a second position for connecting the positive output and the negative output of said corresponding capacitor to said output capacitor thereby producing an output voltage, ##EQU32## and an output current, I.sub.o, of nI.sub.in.
