Gated tunnel diode with a reactive bias stabilizing network for 60 GHz impulse radio implementations

We report on a gated tunnel diode (GTD) and its operation in a 60 GHz pulsed oscillator, also known as a wavelet generator. The wavelet generator operates with the aid of a reactive bias stabilizing network, which minimizes the DC power consumption. This allows for 60 GHz wavelets as short as 56 ps to be produced, with a corresponding energy consumption of 1.0 pJ, which is a factor of 3.6 lower as compared to earlier results. The operation of the GTD is described by a small signal equivalent model deduced from S-parameter measurements.
