Abstract
Galvanic isolators are disclosed herein. An embodiment of a galvanic isolator comprises a generally planar electrically insulating substrate comprising opposing first and second surfaces, the substrate comprising an electrically insulating, low dielectric loss material and having a transmitter coil disposed on the first surface and a receiving coil disposed on the second surface. A transmitter circuit is operably connected to the transmitter coil. The transmitter circuit comprises a first detector that detects a rising edge of an input signal; a first pulse generator that generates a plurality of first pulses upon detection of the rising edge; a second detector that detects a falling edge of the input signal; and a second pulse generator that generates a plurality of second pulses upon detection of the falling edge. A receiver circuit is operably connected to the second receiving coil. The receiver circuit generates a signal that is substantially similar to the input signal based on the first pulses and the second pulses.
