With a total of 3 patents to his name, Garbelli's work showcases his expertise and innovative spirit.
Latest Patents
One of Garbelli's latest patents is a method for driving a voice coil motor with high precision. This method involves controlling the motor that drives a mechanical arm through a control circuit. The circuit sets the output nodes connected to the motor in a high impedance state for a specific time interval. During this interval, the method detects the back electromotive force induced on the motor winding and delivers current pulses to drive the motor. The circuit compares the detected back electromotive force with a target value, regulating the amplitude of the driving current pulses based on the difference between the detected value and a voltage signal representing the desired speed of the arm.
Another significant patent is the method and circuit of soft start and power monitoring for integrated circuits with multiple supplies. This innovation allows for the monitoring of multiple supply voltages using a single external capacitor connected to a pin of the integrated circuit. The design accommodates both externally and internally generated supply voltages, including those with different signs. A logic signal is generated to indicate that all supply voltages have reached pre-established values before enabling the functioning of the integrated circuit, following an initial soft start phase.
