Abstract
A near-field communication circuit of a first NFC device alternates, in low power mode, between: first phases of emission of field bursts and second phases spanning an entire duration separating two successive first phases. Each second phase includes a field detector enabling phase. In one implementation, the field detector enabling phase extends all along a duration of the second phase. In an alternate implementation, the field detector enabling phase is interrupted by field detector disabling phases. Each field detector disabling phase has a duration shorter than a minimum duration of each first phase.
