In this paper, we introduce a multi-V/I converter for low-power true random number generator (TRNG) using a three-Terminal magnetic tunnel junction (MTJ) device. As MTJ devices are probabilistically switched by current, the desired probability of 50% is digitally controlled by digital-To-Analog (D/A) and V/I converters. In the conventional MTJ-based TRNG a highly accurate (and large-power) D/A is required to be tolerate to large temperature variation of MTJ devices. By changing the characteristics dynamically according to the temperature variation, the proposed circuit can reduce the bit precision of the D/A converter while generating the quality of random number as the conventional V/I converter. The circuit is designed with a 65nm CMOS/three-Terminal MTJ model, and the simulation is carried out using HSPICE. As a result, the number of bits of the D/A converter is reduced from 10 bits to 7 bits.
