Abstract:
1. A system for combining a plurality of signals of various phases having a wide frequency range, comprising: a signal transmuter optimized to operate at a first frequency and configured to: receive a first plurality of input signals of different phases, the first plurality of input signals having a second frequency wherein the first frequency is at least ten times greater than the second frequency; and generate at least one output signal based on one or more of the first plurality of input signals, the first plurality of input signals and the at least one output signal having a first voltage less than a second voltage; one or more switches having a turn-on voltage greater than the second voltage and selectively coupling one or more associated capacitors to the at least one output signal such that when the one or more switches is closed the one or more capacitors associated with the one or more closed switches are coupled to the at least one output signal; and a signal generator configured to set a first value of a control signal to inhibit saturation of the at least one output signal, the first value of the control signal associated with a first amount of capacitance based on a difference between the first frequency and the second frequency, wherein: upon the signal transmuter receiving a second plurality of input signals of a third frequency less than the second frequency, the signal generator is further configured to set a second value of the control signal to inhibit saturation of the at least one output signal, the second value of the control signal associated with a second amount of capacitance less than the first amount of capacitance and based on a difference between the first frequency and the third frequency; and upon the signal transmuter receiving a third plurality of input signals of a fourth frequency greater than the second frequency, the signal generator is further configured to set a third value of the control signal to inhibit saturation of the at least one output signal, the third value of the control signal associated with a third amount of capacitance greater than the first amount of capacitance and based on a difference between the first frequency and the fourth frequency; wherein the one or more switches are configured to receive the control signal to selectively open or close the one or more switches based on the first value of the control signal.
