Differential mixer with NMOS/PMOS stack at switching stage
(2012-12-14)
This paper proposes a novel differential mixer topology. The traditional stage of switching is replaced by a stack of NMOS and PMOS transistors combined. A design is given of a 900 MHz down-conversion mixer using a 0.35 ...

Design of a LNA and a Gilbert Cell Mixer MMICs with a GaAsPHEMT technology
(IEEE, 1999-01-01)
The design of a Gilbert Cell Mixer and a low noise amplifier (LNA), using GaAs PHEMT technology is presented. The compatibility is shown for co-integration of both block on the same chip, to form a high performance 1.9 GHz ...
