Abstract: The invention relates to a digital isolator comprising a logic module (20) for receiving an input signal D, and providing command signals (41, 42) to sawtooth modulators. A first sawtooth modulator provides a first sawtooth signal at a node A1 comprising a fast rising edge triggered by a rising edge of a control signal, followed by a slow falling edge, when D equals 1 and comprises a fast falling edge triggered by a rising edge of a control signal, followed by a slow rising edge, when D equals 0. A second sawtooth modulator provides a second sawtooth signal at node A2, inverted with respect to first sawtooth signal. Isolation capacitors (61, 62) are connected to nodes A1 and A2 and are used as isolation barrier and as part of a high-pass filter together with dipoles Z1 and Z2. Threshold comparators (121, 122) provide the output signals S and R.
