Resonant tunnelling diode oscillators with on-chip antenna


The challenge of this proposal is to develop a compact array of oscillator/antenna circuits op-erating at a locked frequency with defined and stable phase conditions enabling MIMO oper-ations. The Resonant Tunnelling Diode (RTD) offers in an ultra-wide frequency range a huge negative-differential resistance that is ideally suited to de-attenuate resonator circuits. RTD based injection locked oscillators co-integrated with on-chip antenna will be developed and fabricated in the frequency range of 0.25 THz < f < 2 THz. In this frequency range we will develop technologies for phase- and frequency locking via sub-harmonic injection.
