Abstract
A method of and an apparatus for reducing noise in a non-Foster circuit having at least a pair of cross coupled transistor devices, each transistor device of the pair of cross coupled transistor devices having a pair of current carrying electrodes. The method and apparatus involves coupling inductors with each pair of the current carrying electrodes of each of the cross-coupled transistor devices in the non-Foster circuit, the inductors also being coupled with voltage and/or current sources associated with or coupled to the non-Foster circuit. The nominal values of the inductors are selected to provide a load asymmetry, so that the load inductor in the input side of the non-Foster circuit has a larger inductance than the load inductor at the output side of non-Foster circuit.
