摘要： A resister network having a negative temperature coefficient (NTC) may be utilized to create a temperature compensated equivalent resistance “R” for a current sensing RC network used in measuring inductor current of a DC-to-DC converter or a general switching regulator that needs to use inductor current as a control signal. The NTC resistor of the RC network effectively compensates for the positive temperature coefficient of the switching regulator inductor's inherent DC resistance (DCR). Keeping the time constants of the RC network and the switching regulator inductor substantially matched improves operation of cycle by cycle based control modes such as peak current sensing by the switching regulator controller in performing peak current control for the DC-to-DC converter.
