ABSTRACT

This chapter introduces a new topology, trigger mode distributed wave oscillator (TMDWO), and discusses its advantages and disadvantages compared to existing topologies. It presents a test structure and the related measurement results of the proposed technique. The chapter describes that the trigger mode distributed wave oscillator proposes an alternative approach for a wave oscillator that can provide unique advantages compared to existing prior techniques. The closed shape of these parallel-running differentially triggered transmission lines, which is shown to be circular, can take any symmetrical geometric form ending up with symmetrical injection points corresponding to the available triggering phases. An important requirement for this triggering oscillator is that its tuning range should cover the estimated frequency range of the traveling wave oscillator. Standing wave oscillators are another group of transmission line oscillators that would utilize transmission line structures. Mutlimode oscillation may occur in Rotary Traveling Wave Oscillator (RTWO) with frequencies that satisfy the periodic boundary condition in the continuous limit.
