Abstract: Control over the operation of an electrically-controlled motor is supported by an interface circuit between the electrically-controlled motor and a near-field radio frequency communication controller. The interface circuit includes a first circuit that receives at least one control set point through a near-field radio frequency communication issued by the near-field radio frequency communication controller. A second circuit of the interface generates one or more electric signals in pulse width modulation based on the control set point.

Abstract: An electromagnetic transponder includes an antenna circuit, a load, and a charge pump transistor having a current path coupled between the antenna circuit and the load. During operation, a retromodulated signal is transmitted at a first level by biasing the charge pump transistor during a first time period such that an impedance of the antenna circuit has a first impedance value and current flows from the antenna circuit to the load. A retromodulated signal at a second level is transmitted by biasing the charge pump transistor during a second time period such that the impedance of the antenna circuit has a second impedance value different than the first impedance value and current flows from the antenna circuit to the load. The retromodulated signals are transmitted at the first and second levels in a sequence determined to transmit information from the electromagnetic transponder.

Abstract: A method of reducing noise generated by pulse width modulation (PWM) signals includes generating a PWM pulse train using a first set of parameter values and modifying the PWM pulse train during a near-field communication so that the PWM pulse train is generated using a second set of parameter values. Modifying the PWM pulse train includes reducing at least one parameter value of the first set of parameter values. The method further includes resuming generation of the PWM pulse train using the first set of parameter values after the near-field communication.
