Embodiment Construction
[0012]The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
[0013]FIG. 1 is a circuit diagram of an embodiment of a boost circuit of the invention. The transistor T1 has a first source, a first gate and a first drain, wherein the first source is coupled to a voltage source VDD. The second transistor T2 has a second source, a second gate and a second drain, wherein the second drain is coupled to the first drain, the second source is grounded, and the second gate is coupled to the first gate to receive an input signal Vin. The capacitor module 11 has a first terminal and a second terminal, and is controlled by a control signal Cs to change a capacitance of the capacitor module for changing the discharge time of the capacitor modu...
