Second Harmonic 210 GHz InP Millimeter Wave Transferred Electron Oscillators

Abstract:
Accurate and efficient calculations of the large-signal AC behavior of second- and third-harmonic InP 'Transferred Electron Oscillators (TE0s) are presented. This is accomplished by combining a novel harmonic balance circuit analysis technique with a hydrodynamic device simulator employing the temperature dependent drift and diffusion equations. The electron transport simulations include a detailed heat flow analysis to update the temperature profile in the device. The nonlinear circuit analysis utilizes a fixed-point iterative method derived from the robust multiple reflection algorithm. To expedite the process and aid in convergence, an acceleration technique is also employed in this algorithm. The associated reduction in computation time allows for the inclusion of a full hydrodynamic treatment of the Transferred Electron Devie (TED) using the first two moments of the Boltzmann transport equation. Comparisons are made with the published experimental data reported by Rydberg on second- and third-harmonic 200-300 GHz InP TEOs. Simulation results for TEOs designed specifically for 210 GHz second harmonic, and 315 GHz third harmonic are presented.
