Relationship between the bias voltage and the received signals and the simulation results for the detected power. (a) Bias voltage in a conventional scheme set outside the NDC region. Direct detection is performed by the non-linearity. (b) Bias voltage in the proposed scheme set within the NDC region. RTD oscillation is locked to the received signals by using the injection-locking phenomenon. (c) I–V characteristics and oscillation power of the RTD oscillator. (d) Simulation results for the bias dependence of the detected power. With coherent detection, the detected power is improved by 24 dB compared to that with direct detection for an input power of −45 dBm and an oscillation power of −11 dBm.
