Problems solved by technology
Since the interface parasitic capacitance corresponding to the substrate has the smallest capacitance value and bears the largest cross-voltage, the parasitic diode corresponding to the substrate is easily turned on, resulting in a greatly limited amplitude of the signal
Since the amplitude of the signal is greatly limited, the amount of energy the signal can carry will also be severely limited

Description
technical field [0001] The invention relates to a transistor, in particular to a transistor which uses a compensation capacitance to increase the range of signal amplitude. Background technique [0002] When a transistor transmits or receives a signal, the amplitude of the signal will straddle all interface parasitic capacitances between the doped region of the drain (source) of the transistor and the substrate on which the transistor is formed, wherein all interface parasitic Among the capacitors, the capacitance value corresponding to the interface parasitic capacitance of the substrate is the smallest and the cross-voltage withstood will be greater than the cross-voltage borne by the other parasitic capacitances of all the interface parasitic capacitances. Since the parasitic capacitance of the interface corresponding to the substrate has the smallest capacitance and bears the largest cross-voltage, the parasitic diode corresponding to the substrate is easily turned on, w...
