New Input Matching Technique for Cascode LNA in 90 nm CMOS for Millimeter Wave Applications

Nanoscale RF CMOS transceiver design

“…On the other hand the effective transconductance of the input stage is reduced also resulting in reduced gain. A new input matching technique for cascode LNAs at mm-wave, reported in [71,72], provides moderately high gain with low NF and good input and output matching . Cascode amplifiers operating at mm-wave have also been reported in [71][72][73][74][75] Increasing the number of stages increases power gain exponentially, but at the expense of power consumption, which increases linearly [66].…”

Therefore, the design of multi-stage amplifiers requires a proper choice of the topology and the biasing of each stage.…”
