摘要： An active clamp device electrically couples first and second nodes in respective first and second supply domains referenced to ground potentials that can be different. The active clamp device comprises first and second active devices controlled by signals respectively referenced to the first and second supply domains that create a short-circuit or low impedance connection between the first and second nodes in normal operation and drive impedance between the first and second nodes high in response to a transient event.

摘要： In an electronic system, a frequency modulator manages clock signals for electromagnetic interference (EMI) reduction. The illustrative frequency modulator comprises a core oscillator, and a clock divider coupled to the core oscillator that modulates frequency of the core oscillator and deterministically spreads clock spectral components of a digital clock signal whereby electromagnetic interference (EMI) is reduced. The frequency modulator further comprises a circuit coupled to the clock divider that receives the digital clock signal, combines the digital clock signal with a data bitstream for transmission across an isolation barrier, and resynchronizes to the digital clock signal.
