Patent attributes
Embodiments feature a circuit that includes a first set of differential switches to generate a first mixer output. The first set includes source terminals, a differential input terminal, gate terminals, and first mixer output terminals. For the first set, the source terminals are coupled to the differential input terminal and the gate terminals are coupled to a first differential oscillator input. The circuit includes a second set of differential switches to generate a second mixer output. The second set of differential switches has source terminals, gate terminals, and second mixer output terminals. For the second set of differential switches, the source terminals of the second set of differential switches are coupled to the first mixer output terminals to receive the first mixer output and the gate terminals of the second set of differential switches are coupled to a second differential oscillator input. The second mixer output terminals couple a filter.
