Abstract
A passive frequency translator with positive conversion voltage gain including at least one input node for receiving an input signal, at least one output node for providing an output signal, and a network which includes capacitors and switches operatively coupled the capacitors and the one or more input and output nodes. The switches are controlled by corresponding clock signals to capture charge of the input signal onto the capacitors and to develop the output signal by performing frequency translation of the input signal by a mixing frequency. The output signal has a net voltage gain relative to the input signal in which energy of the output signal is predominantly derived from energy of the input signal. Furthermore, each of at least three capacitors are configured to capture charge from the input signal and to add constructively to deliver charge to at least one other capacitor coupled to the output node.
