LOW-NOISE ELECTRONIC CIRCUIT SIMULATING THE BEHAVIOR OF AN INDUCTANCE

摘要

An electronic circuit simulating the behavior of an inductance between a respective input node and a reference potential. The electronic circuit comprises a compensation network electrically connected between ground and a source potential and an inverting amplification stage electrically connected to the output of the compensation network. The inverting amplification stage comprises a transistor having a control terminal connected to the input of the inverting amplification stage, a first bias terminal operatively connected to the output of the inverting amplification stage, and a second bias terminal operatively connected to ground. The inverting amplification stage further comprises a feedback capacitance interposed between the first bias terminal and the control terminal of the transistor, and a feedback inductance interposed between the second bias terminal of the transistor and ground.
