ABSTRACT:
A circuit arrangement for signal mixing. One embodiment provides a circuit arrangement for mixing an input signal with at least one carrier signal. The circuit arrangement includes a current source and a current sink. The current source and the current sink have a mixer core coupled between them which provides cross-coupling between mixer input connections and mixer output connections.
