Abstract
This paper aims at demonstrating, for the first time, the use of back bias to improve the analog performance of current mirrors composed by self-cascode structures with 25 nm-long n- and p-type UTBB SOI MOSFETs. The use of back gate bias has shown to enhance the intrinsic gain of p-type devices by about 7 dB, making it higher than the one from a single device with equivalent channel length whereas the mirroring precision has shown to be improved by 20 % with respect to single devices.
