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 coupled to the at least one input node and to the at least one output node, in which the network includes multiple capacitors and switches operatively coupled thereto. 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 in such a manner that DC energy of the input signal is substantially blocked from the output signal. 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.
