Direct Digital Synthesizer Producing A Signal Representing An Amplitude Of A Sine Wave
US Patent:
7436166, Oct 14, 2008
Filed:
Jun 4, 2007
Appl. No.:
11/757726
Inventors:
Wayne E. Solbrig - Broomfield CO, US
Assignee:
Timing Solutions Corporation - Boulder CO
International Classification:
G01R 13/02, H04J 3/06, H03B 21/00, H03K 3/00
US Classification:
324 7655, 370350, 327105, 327119
Abstract:
The invention is directed to a digital phase detector that comprises a splitter and phase shifter to receive a signal of a device under test and produce a first signal that is substantially identical to the received signal and a second signal that is phase shifted relative to the first signal. A first analog-to-digital channel processes the first signal to produce an in-phase and quadrature signals. The second signal is processed by a second analog-to-digital channel to produce a second set of in-phase and quadrature signals. The two sets of in-phase and quadrature signals are used to determine a phase difference between the signal of the device under test and a local oscillator signal associated with the two analog-to-digital channels. The invention is further directed to a direct digital synthesizer that is capable of use within the digital phase detector and in other applications. The direct digital synthesizer comprises a sine look-up table or calculator that provides a digital signal representative of the amplitude of a sine wave at an angle of 2πkJ/M where J is an integer number of cycles of the sine wave, M is an integer number of sine wave data values that represent J cycles of the sine wave, and k is an integer number having a value in a range extending from 1 to and including M.
