Abstract
A circuit to control a motor having phase inputs. A respective control signal for each phase input of the motor is generated such that each phase input is cyclically driven and undriven. Additionally, changes at each phase input relative to a reference potential are measured, and changes at each phase input during time intervals in which noise is expected are ignored: timing information based on the measured changes at the phase inputs is generated, and timing information to carry out the step of generating a respective control signal is used.
