Abstract
A push–push transformer-based oscillator (TBO) adopting a power leakage suppression technique has been proposed. The proposed technique reduces the power loss due to unwanted leakage path without additional DC power consumption, hence improving the output power and DC-to-RF efficiency. The measured output power of the proposed single core oscillator is −4.5 dBm at 270 GHz with 2.1% DC-to-RF efficiency.
Highlights
Terahertz (THz) technologies have been actively studied because of their potential for various applications
Even though with all these potential applications, one big obstacle for THz technology is the lack of compact signal source with high output power and high DC-to-RF efficiency
Zc = 266 Ω helps to suppress the power leakage which leads to approximately 1 dB to 1.5 dB higher output power while achieving 0.3 to 0.6% higher DC-to-RF efficiency compared to those of the conventional push–push transformer-based oscillator (TBO) (Figure 8)
Summary
Terahertz (THz) technologies have been actively studied because of their potential for various applications. Each oscillator core reported in [33,34,35,36,37] is unable to generate an output power of more than −4.8 dBm. the output power and DC-to-RF efficiency of push–push oscillators are the areas that require improvement for the development of THz signal sources.
