Abstract
There is provided a switching circuit for an active mixer. The switching circuit comprises a first pair of parallel switching devices and a second pair of parallel switching devices. The first and second pairs of parallel switching devices are arranged in a stacked configuration between an input node at which an input current comprising a first input frequency signal is received and a pair of differential output nodes. The first pair of switching devices are controlled by a second input frequency signal. The second pair of switching devices are controlled by a phase-shifted counterpart of the second input frequency signal. A common node between the first switching devices of the first and second pairs of switching devices is electrically coupled to a common node between the second switching devices of the first and second pairs of switching devices.
