<p>The present invention relates to an integrated circuit adapted to perform the function of a diode of the DIAC type, said circuit (1) having at least one input terminal (IN) and at least one output terminal (OUT). The circuit (1) comprises at least a first input transistor (T1) having at least a first terminal connected to a fixed voltage reference (GND), at least a second terminal p+ p+45, and at least one control terminal coupled to the input terminal (IN) of the circuit (1). The circuit (1) further comprises at least second (T2) and third (T3) transistors in a current mirror configuration, each having at least a first terminal for coupling to the input terminal (IN) of the circuit (1), and at least a second terminal, and associated control terminals connected together and coupled to at least the second terminal of the first input transistor (T1), the second terminal of the second transistor (T2) being connected to the control terminal of the first transistor (T1). Finally, the circuit (1) comprises at least a fourth output transistor (T4) connected, with first and second terminals, between the output terminal (OUT) and the input terminal (IN) of the circuit (1), said fourth output transistor (T4) also having at least one control terminal connected to at least the second terminal of the third transistor (T3). <IMAGE></p> |
