  • Multiplier and method for mixing signals
    Patent number: 5920810
    Abstract: A multiplier (10) includes a transconductor (14) and a multiplier core (34). The transconductor (14) converts an RF voltage signal to an RF current signal. The RF current signal modulates the quiescent currents flowing in current conducting elements (23, 24), thereby generating a modulated current signal. The modulated current signal is transmitted to the multiplier core (34), where it is combined with an LO signal to generate an output signal. The transconductor (14) and the multiplier core (34) have their current conduction paths separated from each other by the current conducting elements (23, 24).
