CIRCUIT ARRANGEMENT FOR LINEARIZING ELECTRONIC DEVICES Russian patent published in 2006 - IPC H03F1/26 H03F3/19 

FIELD: radio-frequency communication systems for linearizing electronic devices.

SUBSTANCE: proposed linearization circuit arrangement designed to reduce distortions in adaptively connected noise-prone transistor functions in presence of noise sources so as to set up control voltages across transistor input and across transistor common lead actually in order to obtain zero at least at one of following frequencies: (i) differential frequency of two input signals applied to transistor and (ii) input-carrier modulation frequency supplied to transistor; it has first series-connected LC circuit connecting transistor common lead to ground and second series-connected LC circuit connecting transistor input to ground.

EFFECT: improved linearity of amplifiers and mixers used in receivers.
