Abstract
A mixer includes a transconductance circuit and a mixing circuit. The transconductance circuit includes a capacitor and first and second transconductance modules. The first transconductance module converts a single-ended to-be-shifted voltage signal at a first terminal of the capacitor into a first input current signal. The second transconductance module converts a voltage signal at a second terminal of the capacitor into a second input current signal that cooperates with the first input current signal to constitute a differential input current signal pair. The mixing circuit mixes the differential input current signal pair with a differential oscillatory voltage signal pair to generate a differential mixed voltage signal pair.
