Digital Potentiometer Controls Phase Shift: 02/15/96 EDN-Design Ideas / (added 3/03)

Digitally Controlled Phase Shift Using the DS1669: Maxim Application Notes / 975 / Dec-05 (app note added 6/06)

Improving The Full-Bridge Phase-Shift Zvt Converter for Failure-Free Operation Under Extreme Conditions In Welding and Similar Applications: This paper will identify a mechanism that induces power MOSFET failure when the converter operates into a shortcircuit load, a condition that leads to the MOSFET being turned off while its own intrinsic diode is conducting reverse recovery current at the same time as normal channel current. Application Note Microsemi APT9803 ( app note added 04/08)

Phase Shift Radio Direction Finder: (circuit / schematic added 2/03)

Phase Shifter: The classic, swishy sound of the 70s and 80s is coming back. Be ready with this interesting effect. Provides 0 to 180 degrees of phase shift, with a variable sweep control. Works for keyboards and guitar. (circuit design added 11/06)

Phase Shifter: (electronic circuit added 7/03)

Phase Shifter Yields Slope Polarity Detection: 03/14/96 EDN-Design Ideas / (added 03/03) The circuit in Figure 1 uses a phase shifter to provide an output signal that represents the polarity of the slope of an analog signal. You can use it for square-wave shaping of sinusoidal signals or for highpass filtering. V1839 and V1841 can range from 9 to 18V and -9 to -18V, respectively. The unity-gain isolation amplifier IC1 decouples transient spikes from the input source. You can null any dc offset by grounding the two input lines and adjusting resistor R14 until the output signal (pin 10 of IC1) equals 0V....

Scheme extends DDS phase shift resolution: 08/05/99 EDN Design Ideas / (added 11/05) Direct-digital-synthesis (DDS) devices find wide use in instrumentation and communications applications. Rather than using a baseband converter to modulate data in a communications system, you can use a DDS device. Such a device has onboard phase registers that accommodate....
