Abstract:
1. A Quarter-Pumped Distributed Wave Oscillator (QPDWO) system comprising two or more independent electrical conductors forming transmission line loops of a differential medium for traveling wave oscillations; a plurality of cross-coupled inverting amplifiers distributed along said transmission line loops, said inverting amplifiers further comprising non-complementary metal oxide or bipolar devices; a plurality of quarter wave (λ/4) shorted transmission line stubs to provide biasing of said cross-coupled inverting amplifiers; wherein said quarter wave (λ/4) shorted transmission line stubs are distributed symmetrically along said independent electrical conductors; a plurality of resistors in series with the biasing (λ/4) stub to eliminate low-frequency lumped mode of oscillation; and a plurality of varactors to provide tuning for high frequency, high-bandwidth oscillations in the range of at least from about sub-GHz to about THz.
