Signal amplifying apparatus including I/O devices and core devices
The present invention provides a signal amplifying apparatus, for converting a first input signal into a first output signal. The signal amplifying apparatus includes an input stage circuit for receiving the first input signal; a cascoded circuit coupled to the input stage circuit, including a plurality of first cascoded transistors, wherein equivalent oxide thicknesses of the first cascoded transistors are not the same; an output stage circuit has a first input port coupled to the cascoded circuit, and a first output port for outputting the first output signal; and a first capacitor has a first terminal connected to the first output port of the output stage circuit and a second terminal coupled to the cascoded circuit, wherein the second terminal is not connected to the first input port of the output stage circuit.
