Abstract
The present invention relates to a circuit intended to generate a negative conductance NG between two connection terminals A and B, including a first and a second transistor T1 and T2 connected as a differential pair between said connection terminals A and B. According to the invention such a circuit further includes a first active component T3 arranged between the bias and transfer terminals of the first and the second transistor T1 and T2, respectively, and a second active component T4 arranged between the bias and the transfer terminal of the second and the first transistor T2 and T1, respectively. The invention permits to generate a negative conductance which has a value that is substantially constant as a function of the operating frequency of the circuit, which circuit can be completely produced in integrated form.
