Series frequency mixers with phase delay and LO phase shifting pass progressive waves while attenuating regressive waves with low loss.
Equal gate lead lengths and isolated MOS groups keep parasitic capacitances consistent, reducing mixer interference and distortion.
A shallow upper-fin channel implant cuts FinFET flicker noise while improving linearity, drain current, and power efficiency.
Equal gate lead lengths and symmetric MOS layout keep parasitic capacitances consistent, improving mixer linearity under strong RF interference.
Phase-shifted cancellation paths let a gyrator circulator replace ferrites, enabling CMOS-integrated non-reciprocal full-duplex RF routing.
