Characteristics of Series-Connected Resonant Tunneling Diode-Pair Configuration for High Output Power Operation

Herein, a series-connected resonant tunneling diode (RTD)-pair configuration is characterized using the dynamic capacitance characteristics of the RTD. To achieve enhanced output power characteristics, the RTD-pair cell is utilized in the RTD oscillator design to increase the voltage span and current span of the negative differential conductance (NDC) region. The results indicate that not only the output power can be significantly improved compared with the single-RTD oscillator, but also it operates at a small capacitance region, making the RTD-pair oscillator beneficial for high frequency and high output power operation.
