Abstract

The invention discloses a monolithic integrated ring oscillator and frequency divider circuit, which consists of a ring oscillator and a frequency divider based on direct coupling field effect transistor logic. In a chip, the output end of the ring oscillator is connected with the input end of the frequency divider; after applying direct current voltage to the input end, the ring oscillator oscillates, generates sinusoidal signal and outputs; the output sinusoidal signal is used as the input signal of the frequency divider, and the frequency divider outputs divided radio frequency after normal operation. The invention further discloses a processing method for the monolithic integrated ring oscillator and frequency divider circuit. The adoption of the invention can achieve the purposes of reducing chip area and simplifying test procedure.

Description

technical field [0001] The invention relates to the technical field of compound semiconductor circuits, in particular to a monolithically integrated ring oscillator and frequency divider circuit and a processing method thereof. Background technique [0002] The monolithically integrated Enhancement / Depletion Mode High Electron Mobility Transistor (E / D MHEMT) can implement Direct Coupled Field Effect Transistor Logic (DCFL), which can be used to implement high-speed logic circuits. Connect an odd number of inverters end-to-end to form a loop oscillator. When a DC voltage is applied to the input, the ring oscillator oscillates to generate a sinusoidal signal. The ring oscillator can measure the maturity of a process, and the more inverters the ring oscillator includes, the higher the maturity of the process. [0003] The function of the frequency divider is to divide the frequency of the input radio frequency (RF) signal and output it. According to different standards, it is...
