Abstract

The invention provides a terahertz oscillator based on negative resistance enhancement, which comprises a plurality of groups of single-core oscillator circuits for outputting oscillation signals, the plurality of groups of single-core oscillator circuits are connected to the same common endpoint A, and the common endpoint A is connected with an output port through a capacitor C and is connected with a power supply voltage through a transmission line TL1; the multiple groups of single-core oscillator circuits are distributed in an annular shape, and the single-core oscillator circuits are connected through transmission lines TL2 and used for power synthesis, so that the phase noise and the output power of the oscillator are improved. According to the terahertz oscillator based on negative resistance enhancement, the transistor is adopted to replace a source electrode degeneration capacitor, stray capacitance is reduced, the oscillator can generate signals of a terahertz frequency band, meanwhile, the effect of enhancing negative resistance is achieved, and it is ensured that the oscillator can be normally started.

Description

technical field [0001] The invention belongs to the technical field of terahertz oscillators, in particular to a terahertz oscillator based on negative resistance enhancement. Background technique [0002] Terahertz waves have great application potential in the fields of basic research, astrophysics, materials, biomedicine, and modern communication technology, especially in the field of terahertz communications. The characteristics of large amount of information and good directionality make it have obvious technical advantages in the field of wireless communication. In the entire communication system, the frequency source circuit is used to generate terahertz carrier waves. It is one of the most important circuit modules in terahertz communication systems and is also a key component of terahertz systems such as radar, communication, and electronic countermeasures. [0003] There are mainly three ways to generate signals in the terahertz frequency band: one method is based o...
