Embodiment Construction
[0022] This description takes a MOS transistor as an example, but it is not limited thereto. Figure 1A is a schematic diagram of an embodiment of the transistor resistor of the present invention. In the figure, the transistor resistor 10 includes an NMOS transistor 11 , a compensation circuit 12 and a bias circuit 13 . The NMOS transistor 11 operates in the resistive region, that is, its gate-to-source voltage v GS Need to be greater than the threshold voltage (threshold vol tage) V T , and the drain-to-source voltage v DS need to be small. When the NMOS transistor 11 operates in the resistance region, there will be a current i D flows into its drain and out of its source, and i D with v DS The relationship between
[0023] i D =2K(v GS -V T )v DS Formula 1)
