Abstract: The invention relates to a circuit device (1) for realising a non-linear reactive elements scale network, wherein the non-linear elements of the network are pairs of inductive (L) and capacitive (C) components cascade connected between a pair of input terminals and a pair of output terminals. Advantageously in the invention, each component (L,C) of the network is formed by cascade connecting a first (2) and a second (3) transconductance (Gm1,Gm2) integrator with each other.

Abstract: A transimpedance amplifier includes a first and a second power supply terminal for receiving a positive constant supply voltage, wherein the second power supply terminal represents a ground, and an input terminal adapted to be connected to a current source. The transimpedance amplifier further comprises a transistor comprising a control terminal and two further terminals, wherein the input terminal is connected to the control terminal of the first transistor. An inductor is connected between the first of the two further terminals of the transistor and the first power supply terminal, and a bias network is connected between the second of the two further terminals of the transistor and ground. Specifically, the transimpedance amplifier is configured such that the resistance between said first of said two further terminals of said first transistor and said first power supply terminal is small enough, such that said transimpedance amplifier operates as a differentiator.
