OUTPUT STAGE FOR ELECTRONIC DEVICES INTEGRATED ON A SEMICONDUCTOR SUBSTRATE, IN PARTICULAR FOR HIGH FREQUENCY APPLICATIONS AND CORRESPONDING METHOD |
摘要 |
An output stage may include an input terminal receiving an input signal, an output terminal coupled to an external load, and a pre-buffer coupled to the input terminal and including an enable terminal receiving a general enable signal and a first output terminal for supplying a first control signal. The output stage may also include an output buffer including a first final transistor inserted between the supply terminal and the output terminal, and a control terminal coupled to the first output terminal of the pre-buffer for receiving the first control signal, and a first tracking circuit between the supply terminal and the first output terminal of the pre-buffer. The first tracking circuit may include a first capacitor between the supply terminal and a first intermediate node coupled to the first output terminal of the pre-buffer by a switch activated by a first activation signal during a transient of the first final transistor thereby reconstructing a noise of the first reference voltage.
