摘要
The level detector comprises a first capacitance (1) having a charge circuit including a first transistor (3) controlled by the input signal to be detected (Vi) and a discharge circuit. A second capacitance (6) has a charge circuit including a second transistor (8) controlled by the input signal and a discharge circuit having at least one third transistor (17, 18) having pre-set electrical and geometrical characteristics. The above discharge circuits are connected to the respective inputs of a comparator (13) whose output is representative of the difference between the maximum amplitude of the input signal and a reference level depending on said electrical and geometrical characteristics of said third transistor (17, 18).
