Abstract :
The small signal impedance of GaAs/Al(Ga)As double-barrier resonant tunnel diodes has been measured and analyzed over a wide range of frequencies and for various d.c. bias values. The RTD equivalent circuit elements were obtained by measuring the impedance in the bistable region. The cut-off frequency and the self-resonant frequency were calculated and compared with direct measurements.
