Embodiment Construction
[0030] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0031] The present invention provides a high-precision dual-channel positive-terminal current sampling module, and a dual-channel positive-terminal current sampling circuit such as figure 1 As shown; the dotted box part is a dual positive terminal current sampling module, which can be made into a chip;
[0032] The dual-channel positive terminal current sampling module includes resistors R5, R6, and R7 with the same resistance value, the same PMOS transistors MP1, MP2, and MP3, the same PMOS transistors MP4 and MP5, resistor R8, and current sources IS1, IS2, and IS3 with equal currents. ; Among them, MP1, MP2, and MP3 are low-voltage PMOS tubes, and MP4 and MP5 are thin-gate oxide high-voltage PMOS tubes; outside the dotted line frame are the peripheral devices of the chip, which form a dual-channel positive terminal current sampling circuit with the chip; wher...
