Tera Microelectronics Ltd. developed several multi-phase traveling wave oscillator arts such as
Trigger-Mode Distributed Wave Oscillators (TMDWO), Force-Mode Distributed Wave Oscillators
(FMDWO) and Pumped Distributed Wave Oscillators (PDWO). The TMDWO, FMDWO and PDWO
technologies are unique transmission-line based multi-phase oscillator techniques that can provide
very finely spaced (sub-ps) oscillation phases by taping the corresponding points along the
oscillating lines. The even-symmetry feature of the techniques enhances the phase accuracy in
order of magnitudes relative to other transmission-line based traveling and standing wave
oscillators.
The classical transmission-line based wave oscillators suffer from the asymmetry introduced by the
uneven load termination or odd number of crossings along the oscillating loop. These nonidealities
result in severe amplitude and phase variations along the tap points which limit the accuracy and
phase resolution. The novel traveling-wave arts of Tera Microelectronics limit these disturbances to
only process variations by introducing an evenly-symmetric dual-line oscillator topologies.
Some of the unique applications of such high-frequency multi-phase precision signal sources in the
GHz up to THz frequency ranges are THz Imaging Systems, Phased-Array Transceiver Front-Ends,
High-Speed ADCs, Optical and Backplane Serial Communication Links.
