In this paper, δ-doped partially insulated junctionless transistor (δ-Pi-OXJLT) has been proposed which shows that, employing highly doped δ-region below the channel not only reduces the off-state leakage current ( I OFF ) and short channel effects (SCEs) but also reduce the requirements of scaling channel thickness of junctionless transistor (JLT). The comparative analysis of digital and analog circuit performance of proposed δ-Pi-OXJLT, bulk planar (BP) JLT and silicon-on-insulator (SOI) JLT has also been carried out. The digital parameters analyzed in this work are, on-state drive current ( I ON ), I OFF , I ON / I OFF ratio, static power dissipation ( P STAT ) whereas the analog parameters analyzed includes, transconductance ( G M ), transconductance generation factor ( G M / I DS ), intrinsic gain ( G M R O ) and cut-off frequency ( f T ) of the devices. In addition, scaling behavior of the devices is studied for various channel lengths by using the parameters such as drain induced barrier lowering (DIBL) and sub-threshold swing (SS). It has been found that, the proposed δ-Pi-OXJLT shows significant reduction in I OFF , DIBL and SS over BPJLT and SOIJLT devices. Further, I ON and I ON / I OFF ratio in the case of proposed δ-Pi-OXJLT also improves over the BPJLT device. Furthermore, the improvement in analog figures of merit, G M , G M / I DS , G M R O and f T in the case of proposed δ-Pi-OXJLT clearly shows that the proposed δ-Pi-OXJLT is the promising device for mixed signal integrated circuits.
