  • M2077: Programming Guide Integer N PLL Synthesizer 35 - 2500 MHz
    to the same phase comparison frequency. The divided VCO and divided reference signals are then fed into the phase comparator which produces an error signal whose magnitude is proportional to the phase difference between the two signals. The error signal is then passed through a loop filter to produce
  • M2076: Programming Guide Integer N PLL Synthesizer 35 - 1100 MHz
    to the same phase comparison frequency. The divided VCO and divided reference signals are then fed into the phase comparator which produces an error signal whose magnitude is proportional to the phase difference between the two signals. The error signal is then passed through a loop filter to produce
  • Sensorless BLDC Control with Back-EMF Filtering
    This application note describes a sensorless brushless DC (BLDC) motor control algorithm, implemented using the dsPIC (R) digital signal controller (DSC). The algorithm works by digitally filtering the back-Electromotive Force (back-EMF) on each phase of the motor and determining when to commutate
  • Sensorless BLDC Control with Back-EMF Filtering Using a Majority Function
    phase of the motor is filtered to contributed to its use in an increasing number of determine when to commutate the motor drive applications and at higher power levels. voltages. This control technique excludes the need for The BLDC motor is usually operated with one or more discrete, low-pass
