Title:
AN ARBITRARY WAVEFORM SYNTHESIZER USING A FREE-RUNNING RING OSCILLATOR
Document Type and Number:
WIPO Patent Application WO2003084051
Kind Code:
A3
Abstract:
The waveform generator (100) inlcudes a free-running ring oscillator (104), an algebra module (108), a switching module (112) and an output module (114). The free-running ring oscillator (104) includes a plurality of delay elements (120p, 120o, 120c,120b, 120a) connected in a loop and a plurality of taps (TAP 15, TAP 14, TAP 2, TAP 1, TAP 0) disposed between the delay elements, with each tap providing a uniquely phased, oscillating transition signal. The algebra module (108) generates an output signal (136) indicating a first rising edge of the arbitrary waveform in response to an input signal (132).
