摘要: A current sensor having a pair of sense transistors is disclosed. The conducted by power transistor voltage regulator. ratio in size between the and corresponds to scaling factor M. Each has an associated series connected resistor. two resistors are unbalanced provide differential based on sensed at transconductor. transconductor heavy emitter degeneration output substantially proportional primary transistor, proportion determined M resistors.
