Improved current mirror output performance by using graded-channel SOI nMOSFETs

This work introduces the use of Graded-Channel SOI MOSFETs to make analog current mirrors and compare their performance with those made with conventional fully depleted SOI transistors. It is demonstrated that Graded-Channel MOSFETs can provide higher precision current mirror with enhanced output swing. Also lesser modifications of the output characteristics due to the self-heating effect than in conventional SOI MOSFET have been observed.
