Abstract
Blixers, which are a relatively recent development, have not be studied as extensively as many older circuit designs. Here, a blixer is provided that improves linearity and reduces noise over other conventional blixer designs. To accomplish this, the blixer provided here uses a differential amplifier and/or a dummy path within its mixing circuit to perform noise reduction (and improve linearity).
