Design Notes

  • The Vos of the op amp dominates the error when the load current is low. The tolerance of the shunt resistor dominates the error when the load current is high.
  • Increasing R3, R5, and R6 values decreases PMOS power consumption but decreases output (VOUT) range.
  • R2 dominates the power consumption in the system
