Abstract: A crystal oscillation circuit, a gain stage of the crystal oscillation circuit and a method for designing the same are provided. The gain stage includes multiple amplifiers and multiple current-limiting resistors. Input terminals of the amplifiers are coupled together to a first bonding pad, wherein transconductances of the amplifiers are different from each other. The first bonding pad is used for electrically coupling to a first terminal of an oscillation crystal module. First terminals of the current-limiting resistors are respectively coupled to output terminals of the amplifiers in a one-on-one manner, and second terminals of the current-limiting resistors are coupled together to a second bonding pad, wherein the second bonding pad is used for electrically coupling to a second terminal of the oscillation crystal module.
