Output stage for electronic devices integrated on a semiconductor substrate, in particular for high frequency applications and corresponding method
Abstract:
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.
Abstract(Chinese):

输出级可以包括接收输入信号的输入端子，耦合到外部负载的输出端子和耦合到输入端子的预缓冲器，并且包括接收通用使能信号的使能端子和用于提供 第一控制信号。 输出级还可以包括输出缓冲器，其包括插在供电端和输出端之间的第一最终晶体管，以及耦合到预缓冲器的第一输出端的控制端，用于接收第一控制信号，第一跟踪 电源端与预缓冲器的第一输出端之间的电路。 第一跟踪电路可以包括在第一最终晶体管的瞬态期间由在第一最终晶体管的瞬态期间由第一激活信号激活的开关耦合到预缓冲器的第一输出端的第一中间节点之间的第一电容器，从而重构噪声 的第一参考电压。
