Abstract :
The problem of high input impedance of nanoscaled devices is analyzed for the case of a Y-Branch Junction. An electrical nonlinear model of YBJs validated on measured data is used to show influence of source impedance on HF to DC detection performance in YBJ. An impedance matching network is proposed and is proven to increase the detection sensitivity. Multiple 2DEG channels material used to fabricate parallel YBJ´s stacked on one another is also proposed as an alternative solution to mismatch problem. It is shown that using multiple 2DEG the input impedance and reflection coefficient can be decreased but at the price of decrease in sensitivity
