Publication number: 20170070354Abstract: Power and data are transmitted via a transformer including primary side and secondary side. A primary side signal is generated by coupling a first oscillator signal modulated with a data signal with a second oscillator signal that is selectively switched on and off. At the secondary side a secondary signal is generated. A demodulator demodulates the secondary signal to recover the data signal. A rectifier processes the secondary signal to recover a power supply signal controlled by switching on and off the second oscillator.Type: ApplicationFiled: April 26, 2016Publication date: March 9, 2017Applicant: STMicroelectronics S.r.l.Inventors: Egidio Ragonese, Nunzio Greco, Giuseppe Palmisano
