Abstract

Rezonantna tunelska dioda (RTD) je vrlo popularan element u izvedbi visoko frekvencijskih oscilatora zbog njene visoke brzine rada. U ovom završnom radu trebalo je napraviti razvojni alat za RTD u Keysight ADS programu i jednostavni oscilator temeljen na negativnom otporu i implementiran s RTD. Oscilator je uspješno napravljen jer se s istosmjernim naponom napajanja dobivaju sinusne oscilacije. Demonstriran je sklop s frekvencijama osciliranja od 1 GHz i 100 GHz. Dobivena izlazna snaga je zadovoljavajuća, reda veličine ~mW, ali korisnost je niska, što zahtijeva dodatna poboljšanja na razini elementa i sklopa.

Abstract (english)

Resonant tunnel diode (RTD) is very popular device in designing high frequency oscillators due to its high speed. The aim of this thesis was to develop a design kit for RTD in Keysight ADS environment and use it to design a simple negative-resistance oscillator based on RTD. The oscillator is successfully made and with DC bias voltage sinus oscillations are achieved. The circuit is demonstrated for oscillation frequencies of 1 GHz and 100 GHz. The resulting oscillating power is satisfactory, around ~mW, but the efficiency is low, which demands further improvements in terms of device and circuit design.
