Abstract
A true random number generator with a dynamic compensation capacity comprises a loop control logic, a shift register, a sensitive amplifier and a load matching unit. The sensitive amplifier comprises a first PMOS transistor, a second PMOS transistor, a third PMOS transistor, a fourth PMOS transistor, a first NMOS transistor, a second NMOS transistor and two NMOS arrays. Each NMOS array comprises a third NMOS transistor, a fourth NMOS transistor, a fifth NMOS transistor, a sixth NMOS transistor, a seventh NMOS transistor, an eighth NMOS transistor, a ninth NMOS transistor, a tenth NMOS transistor, an eleventh NMOS transistor, a twelfth NMOS transistor and a thirteenth NMOS transistor. The load matching unit comprises a first D flip-flop and a second D flip-flop and is connected at an output terminal and an inverted output terminal of the sensitive amplifier. The true random number generator has the advantages of simple feedback regulation and high robustness.
