Junctionless Transistors Based Current Mirrors: Analog Figures of Merit Dependence on the Devices Width

In this paper, a comparison between the basic current mirror configurations (Common Source, Cascode, and Wilson) based on nMOS Junctionless Nanowire Transistors (JNTs) is performed for the first time through TCAD simulations. Those building blocks are biased at the same conditions in the output stage by a fixed voltage, while a normalized current is applied in the input stage. In that regard, the main figures of merit of the current mirrors, such as current transfer ratio and small signal output resistance, are analyzed in order to understand the analog behavior of the JNT and its application as a current source building block.
