摘要： A system can provide current detection in an integrated circuit (IC) chip while compensating for variations in circuit components resulting from process, voltage supply, temperature, or combinations thereof. The system can include the IC chip that has a power switch circuit that includes a power circuit path including a first transistor connected to a power source through a first conductive trace that has a first resistance value, and to a load by a second conductive trace having a second resistance value. A current detection circuit is configured to compensate for the variations in the power switch circuit using a sense circuit path that is configured to match process, voltage supply, and temperature variations in the power circuit path.

摘要： A current sense resistor and a method of manufacturing a current sensing resistor with temperature coefficient of resistance (TCR) compensation is disclosed. The resistor has a resistive strip disposed between two conductive strips. A pair of main terminals and a pair of voltage sense terminals are formed in the conductive strips. A pair of rough TCR calibration slots are located between the main terminals and the voltage sense terminals, each of the rough TCR calibration slots have a depth selected to obtain a negative starting TCR value observed at the voltage sense terminals. A fine TCR calibration slot is formed between the pair of voltage sense terminals. The fine TCR calibration slot has a depth selected to obtain a TCR value observed at the voltage sense terminals that approaches zero. The resistor can also have a resistance calibration slot located between the pair of main terminals. The resistance calibration slot has a depth selected to calibrate a resistance value of the resistor.

摘要： Two magnetic field sensors, H1 and H2, ratiometiic with respect to their common supply and matched for the thermal coefficient of their magnetic sensitivities, are located at the airgaps of two identical gapped cores. The current to be measured, I M , is carried by a winding encircling both cores, and thus establishing a field B(I M ) at both airgaps. Each core additionally carries an auxiliary winding connected in series with the auxiliary winding of the other core, in such a way that an accurate reference current, I R , flowing through both of them will result in an additional magnetic field component, B(I R ) , summing to B(I M ) at one of said airgaps, while subtracting from it at the other airgap. Adder and subtractor circuits thus generate two output signals: one proportional to B(I R ) only and the other proportional to B(I M ) only. A feedback loop arranged to held at a constant value the output voltage proportional to B(I R ) by proportionally adjusting the common supply to both sensors produces the effect that drifts with temperature, of the magnetic sensitivities of the two sensors, are intrinsically compensated for.
摘要翻译：两个磁场传感器H1和H2相对于它们的公共电源是成熟的，并且它们的磁敏感度的热系数相匹配，位于两个相同间隙芯的气隙处。要测量的电流IM由包围两个铁芯的绕组承载，从而在两个气隙处建立场B（IM）。每个磁芯另外还带有一个与另一个磁芯的辅助绕组串联的辅助绕组，使得流过它们两个的准确参考电流IR将导致额外的磁场分量B（IR）在所述气隙中的一个处求和B（IM），而在另一个气隙处从它减去。因此，加法器和减法器电路产生两个输出信号：一个仅与B（IR）成比例，另一个与B（IM）仅成比例。通过按比例调整两个传感器的公共电源，将反馈回路保持在一个恒定值，输出电压与B（IR）成比例，产生两个传感器的磁灵敏度随温度漂移的影响，从而得到固有补偿。

摘要： A dynamic calibrating current sensor control system includes an input power supply (202) that generates an input current and a current sensor (208) interposed between the input power supply and the load. The current sensor is configured to output at least one current signal indicating a level of current delivered to the load. The dynamic calibrating current sensor control system also comprises an electronic switching control circuit (212) that generates at least one control signal to selectively connect the input power supply to the load, and an electronic drift suppression circuit (214) in signal communication with the current sensor and the switching control circuit. The drift suppression circuit is configured to generate a corrected current signal in response to applying an offset value to the current signal. The offset value cancels the drift current from the current signal in response to connecting the input power supply to the load.
